Dr. SeungYeon Kang Gives Seminar over Advanced Laser-Materials-Processing Techniques for Nanofabrication of Functional Materials and Energy Harvesting Devices

SeungYeon Kang, Ph.D. presented a seminar Friday, March 6, over, “Advanced Laser-Materials-Processing Techniques for Nanofabrication of Functional Materials and Energy Harvesting Devices.” Dr. Kang is a Program Manager for NSF’s SHAP3D additive manufacturing center at the University of Connecticut.

Abstract: Increasing number of novel materials, structures and device are being designed every day to revolutionize our future. Accordingly, new fabrication methods to complement the designs must be developed for actual realization of the devices. In this talk I’ll start by discussing the use of ultrafast lasers for advanced materials processing techniques and the significance of developing new nanofabrication methods for cost-effective manufacturing and rapid prototyping with high accuracy. The focus of my talk will be on a novel direct laser writing technique that enables fabrication of 3D metal-dielectric nanocomposite structures of tunable dimensions ranging from hundreds of nanometers to micrometers. This true 3D patterning technique utilizes nonlinear optical interactions between chemical precursors and femtosecond pulses to go beyond the limitations of conventional fabrication techniques that require multiple postprocessing steps and/or are restricted to fabrication in two dimensions. The first part of the talk will end with a further discussion on possible applications including metamaterials, graphene-based devices and etc. In the shorter second part of the talk, I’ll introduce a relatively new material of research interest called piezoelectrochemical materials and another advanced laser-materials-processing technique that utilizes laser induced forward transfer (LIFT). I’ll end with a discussion on how one can use these two research areas to develop energy harvesting devices that convert ambient mechanical energy into electrochemical energy.

Dr. Guru Dinda Gives Seminar over Accelerated Discovery of New Ni-based Superalloys Via Additive Manufacturing for Advanced Turbine Engines

On Monday, March 2, Dr. Guru Dinda gave a seminar over, “Accelerated Discovery of New Ni-based Superalloys Via Additive Manufacturing for Advanced Turbine Engines.” Dr. Dinda is an Assistant Professor of Mechanical Engineering at Wayne State University.

Abstract: Due to the ever-increasing demands for energy efficiency in gas turbines for power plants and aircraft engines, new Ni-based superalloys remain under development. Our current level of theoretical and empirical understanding does not usually permit one to predict the structures and resulting properties of these multicomponent materials. Consequently, the discovery and optimization of many materials comprise trial-and-error experiments. Given the vast universe of potential alloys that can be created by combining various elements from the periodic table, the conventional method of synthesizing and testing samples one at a time is too slow for exploring the broad range of novel materials. Here I disclose a high-throughput alloy development procedure based on the direct laser metal deposition principle coupled with CALPHAD-based solidification modeling that will expedite the alloy discovery process by 100 to 1000 times compared to the current one at a time alloy development practice. In the current alloy development research, the testing of the mechanical properties of the new alloys comes at the later part of the alloy development process. Tensile testing of thousands of conventional test specimen requires a long time and adequate resources. This limits the exploration of a very large set of alloy library. Here I propose a sample fabrication and testing methodology of thousands of miniaturized tensile test samples in a few days at the early stage of the alloy development. It is expected that the proposed high-throughput alloy development technique will be used extensively to explore various alloy libraries to discover many new high-performance materials for structural and functional applications.

Dr. Sergey Averkin Gives Seminar Over Kinetic Simulations of Non-equilibrium Phenomena in Partially Ionized Plasmas

Sergey Averkin, Ph.D., a Research Scientist from Tech-X Corporation, gave a seminar Friday, February 28. He spoke about, “Kinetic Simulations of Non-equilibrium Phenomena in Partially Ionized Plasmas.”

Abstract: Partially ionized plasmas have many applications in science and engineering. The examples of applications include space propulsion, material processing including production of nanomaterials, ion sources, display panels, medicine. Modeling and simulation of non-equilibrium chemically reacting plasmas is a challenging problem owing to the presence of complicated plasma chemistry and coupling between volume, surface, and transport non-equilibrium processes. Simulation approaches span from volume averaged global models that incorporate thousands of chemical reactions and include simplified assumptions regarding transport to computationally expensive kinetic simulation methods that allow to calculate detailed information of plasma transport and usually employ simplified chemical models to speedup simulations.

The first part of the talk presents a Global Enhanced Vibrational Kinetic (GEVKM) model and its application to the simulation of an RF discharge chamber of a new High Current Negative Hydrogen Ion Source developed by Busek Co. Inc. and WPI. The GEVKM is supplemented by a comprehensive set of surface and volumetric chemical processes (22 species and more than 1000 chemical reactions) governing vibrational and ionization kinetics of hydrogen plasmas. The model is computationally efficient. It was used in parametric studies with thousands of points in parameter space.

The second part of the talk outlines new developments in the Particle-in-Cell and Direct Simulation Monte Carlo methods (PIC/DSMC) that are used to model partially ionized plasmas and rarefied gases that are described by kinetic equations coupled with the Poisson equation. The PIC/DSMC method can provide detailed information of the distribution functions of plasma components in complicated geometries. The applications of the PIC/DSMC method to simulations of flows inside nanonozzles and around CubeSat are presented. In addition, novel simulations of plasma assisted growth of nanoparticles using PIC/DSMC method are discussed.

Dr. Cheng Huang Gives Seminar over Data-Driven and Reduced Order Modeling of Combustion Dynamics in Propulsion Systems

On Monday, February 24, Dr. Cheng Huang gave a seminar over, “Data-Driven and Reduced Order Modeling of Combustion Dynamics in Propulsion Systems.” Dr. Huang is an Assistant Research Scientist in Aerospace Engineering at The University of Michigan.

Abstract: Combustion dynamics is characterized by the coupling between flow dynamics, chemistry, and acoustics. In propulsion systems, this complex coupling can lead to combustion instabilities and cause devastating engine failures. Even though modern computational capabilities have moved beyond the empirically-based design analyses of the past, high-fidelity (e.g. Large Eddy) simulations of full-scale engines remain out of reach for day-to-day engineering design applications. This drives the motivation to develop accurate and low-cost model to simulate dynamics in complex propulsion systems, especially for the space exploration initiatives. This talk will present recent work on computational modeling of turbulent reacting flow for engineering applications with emphasis on progress in Data-Driven and Reduced Order Modeling framework development for reacting flow problems to enable efficient prediction of combustion dynamics in liquid fueled rocket combustion systems. Specific topics include 1) high-fidelity (e.g. Large Eddy) simulations of turbulent reacting flow for engineering applications; 2) development and successful demonstration of Multi-fidelity Modeling Framework for design applications of large scale combustion devices and 3) advancement in the state-of-art in Data-Driven and Reduced Order Modeling for complex dynamical systems to produce orders of magnitudes accelerated accurate models from high-fidelity data.

Biography: Dr. Cheng Huang is currently an Assistant Research Scientist in Aerospace Engineering at University of Michigan – Ann Arbor. Before that he worked as a PostDoctoral Research Assistant in the School of Aeronautics and Astronautics at Purdue University. Dr. Huang received his PhD in Mechanical Engineering from Purdue University in 2015, his M.S. in Mechanical Engineering from Purdue University in 2012. He completed his undergraduate education in Mechanical Engineering from Shanghai Jiaotong University in 2011. He specializes in computational modeling of turbulent reacting flows in complex combustion systems (e.g. rocket and gas turbine engines). His work primarily focuses on high-fidelity Large Eddy Simulation (LES), Data-Driven and Reduced Order Modeling (ROM) of combustion dynamics in aerospace propulsion systems.

Dr. Woong-Yeol Joe Gives Seminar Over Design and Control of a Camber Morphing Wing Aircraft

On Friday, February 21, Woong-Yeol Joe, Ph.D. gave a seminar over, “Design and Control of a Camber Morphing Wing Aircraft.” Dr. Joe is an Associate Professor from the Department of Mechanical and Manufacturing Engineering at Tennessee State University.

Abstract: Wing morphing technologies in general aim to optimize aircraft’ efficiency by changing and adjusting the shape of wings in compliance to corresponding flight conditions. Among many types of wing morphing, suggested variable camber compliant morphing in airfoil morphing enables aircraft to have seamless, conformal, and energy and noise effective change of wing geometry that significantly reduces drag force or lift-drag ratio. Unlike typical approaches of using smart materials or partial morphing of trailing-edge, mechanism-driven camber morphing wing via linear actuators enables fixed wing aircraft wing to adjust camber rates conformally, dynamically, and firmly along the wing span. For realization of actual flight and control of camber morphing wing aircraft, it is of interest (1) to investigate the nature of structural and aerodynamical behaviors of camber morphing wings while flight, (2) to study difference and similarity between the conventional wing and the camber morphing wings in control aspects, (3) to design and implement the skin structure of camber morphing wings along with characteristics of 3D printed structure. This presentation covers overview of morphing technologies, motivation and benefits of camber morphing, design of control allocation aspect of camber morphing wings, and design and implementation of skin structure for camber morphing wings with perspectives of 3D/4D printing.

Biography: Dr. Woong Yeol Joe is a tenured Associate Professor in the Department of Mechanical and Manufacturing Engineering at Tennessee State University (TSU), Nashville TN. Currently, he is doing his first sabbatical year at ORNL (Oak Ridge National Laboratory), Knoxville TN focused on 3D/4D manufacturing technology.

Dr. Heydari Gives Seminar Over Theory of Reinforcement Learning and Its Practice in Robotics and Autonomous Systems

Ali Heydari, Ph.D., an assistant professor of Mechanical Engineering at Southern Methodist University, gave a seminar on Monday, February 17th. He spoke about, “Theory of Reinforcement Learning and Its Practice in Robotics and Autonomous Systems.”

Abstract: Ali Heydari received his B.S. and M.S. degrees from Sharif University of Technology, Iran, in 2005 and 2008, respectively, and his Ph.D. degree from the Missouri University of Science and Technology, Rolla, Missouri, in 2013. He is currently an assistant professor of mechanical engineering at the Southern Methodist University, Dallas, Texas. His research is mainly focused on Adaptive Dynamic Programming and on applications of this machine learning scheme in robotics and autonomous systems. He serves on the editorial boards of IEEE Transactions on Neural Networks and Learning Systems and IEEE Transactions on Vehicular Technology.

Biography: Control plays the role of enabler in mechanisms in which, a parameter “changes”. For decades, a controller design was deemed successful, when the desired motion/change was achieved. However, today, the standards are much higher. “Qualities” including low energy consumption for a better range, human friendliness for safe and efficient interactions, high accuracy and productivity, high robustness to uncertainties and imperfections, and small footprint on environment are important “requirements” now.

Adaptive Dynamic Programming (ADP), also called Reinforcement Learning (RL), has a great potential to win in these new domains. The reason is, ADP/RL is motivated by nature, that is, the perfect way humans learn to operate machinery and control mechanisms. As an “intelligent control” tool, however, ADP/RL has been subject to shortcomings both in terms of its “rigor” (guarantees of desired performance) and its “scalability” (possibility of extension to challenging problems, beyond toy examples). An overview of my past and future research activities on resolving these two deficiencies will be presented in the seminar. Moreover, applications of the developed methods in challenging problems of autonomous systems and robotics will be discussed, including human-machine interaction and co-design of mechanisms and their controllers.

Dr. Jeongmoo Huh Gives Presentation Over Micro Propulsion Systems for the Next Generation Space Missions

On Friday, February 14th, Dr. Jeongmoo Huh gave a presentation over, “Micro Propulsion Systems for the Next Generation Space Missions.” Dr. Huh currently works in the Space Engineering Department in the Faculty of Aerospace Engineering at Delft University of Technology as a visiting researcher.

Abstract: Many miniaturized satellites have recently been launched and proved the feasibility of distributed space systems in space missions with improved revisit time, the time elapsed between observations by satellites, at an extremely low cost. Most preliminary small-scale satellites such as CubeSat and PocketQube, however, were either not equipped with a micro-propulsion system for its altitude/orbit control or not ready for various space missions due to inherent theoretical performance limitations of space propulsion systems that currently exist as well as limited performance achievement of micro propulsion systems. Not only normal operation of miniaturized satellites but also the next generation space mission using CubeSat/PocketQube will not be feasible without successful downsizing of space propulsion systems and their performance improvement.

The seminar will start with general principles of several chemical rockets and difficulties of downsizing of chemical rockets, and report how a chemical rocket was successfully miniaturized including a photolithography process, a MEMS (Micro-electro-mechanical Systems) based fabrication technology, and catalyst manufacturing process as well. Performance of thruster generation and propellant decomposition efficiency of 50 mN class MEMS-based monopropellant micro thrusters will be discussed based on experimental data showing how much performance was improved by using a blended propellant and regenerative micro cooling channels in micro scale thruster systems.

This will be followed by an introduction to electrospray micro colloid propulsion, one of space electric propulsion systems, which has arguably the highest specific impulse performance, up to a range of 1,500-7,000 s depending on electric power supplied. The different nature of the working principle of the system and its performance characteristics compared with chemical one will be identified. Pros and cons of chemical and electric propulsion systems will be discussed with inherent performance limitation of both propulsion systems, and a new system configuration for space micro propulsion will be suggested to meet the performance requirement of miniaturized propulsion systems for the next generation space missions, an interplanetary mission of miniaturized satellites.

Biography: Dr. Jeongmoo Huh currently works in Space Engineering Department in the Faculty of Aerospace Engineering at Delft University of Technology (TU Delft) in the Netherlands as a visiting researcher starting from July 2019. In Delft, He’s working on high energetic gel phase novel propellant development for space propulsion applications. Before joining the group, he worked as a postdoctoral researcher at Queen Mary, University of London (QMUL), in the UK from April 2017 to June 2019 participating in an electric propulsion project funded by the EU. The project was about high-performance low-cost disruptive propulsion technology using electrospray colloid propulsion for small-scale satellite applications. There was a consortium for the project and it was composed of a university, QMUL, and three different space-related companies, AirBus in the UK, NanoSpace in Sweden, and SystematIC in the Netherlands. The successful outcome is now on its way to commercialization. Dr. Huh stayed in Daejeon, South Korea for about 5 years from Feb 2012, for his graduate course and one year of postdoc experience. He received an M.S./Ph.D. degree in the Department of Aerospace Engineering from Korea Advanced Institute of Science and Technology (KAIST) in Daejeon in Feb 2016. For his Bachelor’s degree, he studied in the Department of Aerospace and Mechanical Engineering at Korea Aerospace University, Goyang, South Korea, from March 2008 to Feb 2012. His research topic in graduate school was about micro-scale chemical space propulsion for Nano-satellite applications, for which a MEMS(Micro-Electro-Mechanical Systems) fabrication process was designed and employed, validating successful manufacturing and operation of 50 mN class monopropellant thrusters with the suggested development procedure. As a postdoctoral researcher at KAIST, he also experienced classical size monopropellant, bipropellant, and hybrid propellant rockets and had hands-on experience on its application to sounding rockets, sounding rocket flight testing, and numerical code development for propulsion performance and flight performance estimation. One of his journal papers related to the micro chemical propulsion was selected as the best paper in Journal of Micromechanics and Microengineering at 2013 and 2014, and several conference papers related to micro propulsion, sounding rockets, and micro reactors were the best paper awarded and selected for further manuscript work at several international conferences held in the UK, France, Korea, and the US. Overall, chemical and electric space propulsion, sounding rocket systems, MEMS-based combustion and propulsion, and new energetic materials and novel propellants are what he has experienced and where his expertise lies in.


Dr. Imraan Faruque Presents Seminar over Current Research

Imraan Faruque, Ph.D., gave a presentation on Monday, March 25, 2019 on how biologically-driven flight control strategies can inform unmanned aerial vehicle swarms. Dr. Faruque is an assistant professor for the Department of Mechanical and Aerospace Engineering at OSU.

Abstract: This seminar introduces a framework for deriving feedback design principles that can enable insect-based flight control approaches on unmanned aerial systems (UAS) and engineered extensions to groups of UAS. The seminar begins by establishing flight dynamics models of dipteran flapping wing insects, combining automated high-speed videography measurements of freely flying insects, experimental aerodynamics results, rigid body dynamics, and system identification techniques to distill high fidelity flight dynamics models into computationally-tractable models applicable to flight control analysis.  Methods to extract models of the closed loop controllers implemented on insects from free flight trajectories are discussed.  Linear matrix inequalities are applied to interpret the controllers into design principles that can translate the extracted controllers into those appropriate for engineered vehicles, and improvements in experimental techniques to quantify multi-agent aerial insect behaviors.  Control-theoretic definitions of reachability are applied to the aerodynamic mechanisms involved in insect-scale flight control and gust response, leading to a theoretic framework for the gust response properties of closed-loop flight control and the engineered design of gust-aware flight controllers.

Biography: Imraan Faruque’s research interests include reduced-order models of complex systems, biologically inspired locomotion and control systems, unmanned aerial systems, and flight dynamics and control.  Dr. Faruque’s specialization is in dynamic models of flying insect feedback, and in reduced order flight dynamics models that can concisely capture the dynamic properties of insect flight control, where his work has led to over 40 publications, including numerous best paper awards and patents. Dr. Faruque is currently an Assistant Professor at Oklahoma State University’s Department of Mechanical and Aerospace Engineering, with an appointment as Assistant Research Professor in the University of Maryland’s Department of Aerospace Engineering.  He is an honors alumnus of Virginia Tech, and received his MS (2010) and Ph.D. in Aerospace Engineering in 2011 from the University of Maryland. He previously held research positions at the Army Research Lab, the Air Force Research Lab, and at General Electric Aircraft Engines.

Dr. Zuo Presents Seminar at OU

Dr. Jian Zuo gave a seminar over drug discovery for hearing loss on Thursday, March 14th at OU. Dr. Zuo is a chairman and professor from the Department of Biomedical Sciences at Creighton University School of Medicine.

Abstract: Hearing loss caused by aging, noise, cisplatin toxicity, or other insults affects 360 million people worldwide, but there are no Food and Drug Administration–approved drugs to prevent or treat it. We first performed high-throughput screens for small molecules that prevent cisplatin-induced hearing loss in a cochlear derived cell line. The hit compounds were further validated in cochlear explants, zebrafish lateral-line neuromasts in vivo, and eventually in mouse and rat’s cochleae in vivo. We have so far identified and characterized several potent compounds that exhibit protection against not only cisplatin but also antibiotics and noise-induced hearing loss. We further investigated several targets of top compounds in knockout mouse models. To treat hearing loss, we first developed genetic mouse models in which hair cell regeneration occurred at adult ages. Based on the genetic manipulations, we performed high-throughput screens of small molecules that mimic the genetics models. We further tested these top compounds in adult mice for hair cell regeneration. Combinatory applications of these top compounds could provide therapeutic intervention of hearing loss in clinics.

Abstract: Compact separation technology has continuously improved significantly in recent years, due to its applications in a variety of industries, such as Oil & Gas, Chemical, Environmental, and Aerospace. The conventional separators that are based on gravity, are bulky, heavy and expensive, which are being replaced by compact separators that have smaller foot-print, higher productivity and are less expensive to procure and operate. Gas-Liquid Cylindrical Cyclone (GLCC©) separator is one such compact separator that is simple and easy to install and operate with more than 6800 applications including subsea. The presentation covers various aspects of design modifications of GLCC separators and quantifying its performance under the limiting conditions using control strategies. Details of experimental research conducted to investigate the two undesirable phenomena, namely, Liquid Carry-Over and Gas Carry-Under are presented. The Structural integrity analysis of the GLCC inlet section is conducted using the FEA and the design modifications are validated using CFD simulations. A comparative study of the FEA analysis results and Fluid-Structure Interaction analysis results is presented. In addition, different mechanistic models developed to quantify the LCO and GCU of the GLCC are discussed. Finally, short-term and long-term research goals are presented along with guiding principles of teaching philosophy.
