Dr. Aman Satija Gives Seminar Over Development and Application of Laser Spectroscopy for Gas-Phase Diagnostics

Last Friday, Dr. Aman Satija gave a seminar over, “Development and Application of Laser Spectroscopy for Gas-Phase Diagnostics.” Dr. Satija is a Research Engineer at the Applied Laser Spectroscopy Lab at Purdue University.

Abstract: Laser diagnostics are employed in combustion and propulsion research due to their non-intrusiveness to the flow field, high-accuracy, and fast response time. Laser based techniques are used for measuring important flow parameters such as temperature, pressure, velocity and species concentration. Some laser methods, based on linear optical processes, such as absorption spectroscopy and particle image velocimetry have matured to an extent that they are commercially available and are being actively used in the industry. In this seminar, Dr. Satija will provide a survey of his research in quantitative non-linear spectroscopic methods and high-repetition rate diagnostics. He will: a) discuss the similarities and differences between various types of nanosecond coherent anti-Stokes Raman scattering (CARS) methods along with some applications b) present recent developments in chirped-probe-pulse femtosecond CARS for 5 kHz thermometry c) describe the principle of polarization spectroscopy and present its application towards measurement of minor species in reacting flows d) discuss progress of high-average power high-repetition lasers and present examples of high-repetition rate diagnostics in turbulent atmospheric and high- pressure combustion and e) comment on the challenges and opportunities of quantum modeling of nonlinear light-matter interaction in context of atoms and small molecules.

Dr. Bin Xu Gives Seminar Over Physics-based/ Data-driven Diesel Engine Waste Heat Recovery and Hybrid Vehicle Propulsion System Energy Management for Fuel Efficiency Improvement

Dr. Bin Xu, a Research Assistant Professor for the Department of Automotive Engineering at Clemson University, gave a seminar on Monday, March 8 over “Physics-based/ Data-driven Diesel Engine Waste Heat Recovery and Hybrid Vehicle Propulsion System Energy Management for Fuel Efficiency Improvement.”

Abstract: For internal combustion engines, the engine efficiency is generally below 40% for gasoline engines and 50% for diesel engines. For a heavy-duty diesel engine, around 40-60% of energy is wasted as heat via exhaust gas, EGR cooler, and coolant. Waste heat recovery (WHR) techniques have the potential to achieve the fuel economy and emission reduction goals for its mature technology and high efficiency. Conventional modeling and power analysis in WHR system focus on static engine operating conditions, whereas engine experiences torque variation even at highway conditions. To overcome the research gaps in dynamic modeling, control and optimization over highly transient engine operating conditions, a series of systematic modeling, control, optimization and experimental validation work are conducted to understand the characteristics of the WHR system and maximize the waste energy recovery. According to dyno test result, 3% absolute break thermal efficiency improvement is achieved in a 13L diesel engine with the developed WHR system.

The automotive industry is in the pace of reforming from petroleum-dependent to renewable energy-dependent for better sustainability and environmental friendly goals. Hybrid Electric Vehicle (HEV) is the first step towards the propulsion system electrification. With a given vehicle hardware, one key factor affecting the fuel consumption is the energy management of the engine and the electric motor, which could lead to 20% fuel consumption variation. Conventional energy management strategies (EMS) are either rule-based or model-based. Rule-based EMS lacks optimization and leaves large room for fuel saving. Model-based EMS like model predictive control depends on reduced order models, which require long time to build for the complex vehicle propulsion system and sacrifice model accuracy for short computation time. Model- free reinforcement learning (RL) based EMS is proposed to address the optimization concern of rule-based methods and reduced order model development concern of model-based methods. Parametric study is conducted to interpret the RL state/ action/ reward selection and their impact on fuel economy, which is supported by value functions and policy maps. An ensemble RL framework is proposed to integrate RL with conventional EMS methods for better fuel economy. Moreover, two warm start methods are proposed to reduce the learning time of RL as much as 68%.

Bio: Bin Xu joined the Department of Automotive Engineering, Clemson University in March 2020 as a Research Assistant Professor. Prior to coming to Clemson, Dr. Xu was a Research Scientist at the Stanford University. Dr. Xu received his B.S. degree from Hunan University China in 2013, Ph.D. from Clemson University in 2017, both in Automotive Engineering. Dr. Xu’s research focus on propulsion system modeling and control, particularly in the areas of physics-based and data-driven modeling, control, and fuel efficiency optimization. Over the past 4 years, Dr. Xu has published 31 peer-reviewed articles including 13 first-authored journal articles and his research have been cited 337 times in Google Scholar.

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.

Biography: Dr. Sergey N. Averkin received the B.S. and M.S. degrees in applied mathematics and physics from the Moscow Institute of Physics and Technology, Moscow, Russia, in 2007 and 2009, respectively, and the Ph.D. degree in aerospace engineering from the Worcester Polytechnic Institute (WPI), Worcester, MA,  in 2015. From 2015 to 2016, he was a Post-Doctoral Fellow and an Adjunct Teaching Professor at WPI. In 2018 Dr. Averkin was a Research Associate at the University of Colorado Boulder. Currently he is a Research Scientist at the Tech-X Corporation, Boulder, CO, USA. His current research interests include advanced numerical simulations of nonequilibrium phenomena in chemically reacting rarefied gases and plasmas. Applications of such simulations include space propulsion, mass and heat transport at micro and nano scales, ion sources, plasma processing. Dr. Averkin is a member of the American Physical Society (APS) and the Institute of Electrical and Electronics Engineers (IEEE).
