Paul Palies

Paul Palies

Paul Palies is Associate Professor at UTSI and the founding director of the Combustion and Propulsion for Aviation Research Center (C-PARC) at UTSI. His research is in reacting fluid dynamics with specializations in aeronautical propulsion research and physics of premixed swirling flames. He developed an expertise in combustion dynamics applied to laboratory scale combustors and jet engines with a demonstrated experience in acoustics, combustion, and fluid dynamics. His published work has focused on understanding key physics and passive control strategies in this context as demonstrated by a patent, a book and several widely cited articles. He graduated from Ecole Centrale Paris in aerospace and from University of Paris XI in mechanics-physics. He has broad-band fundamentals knowledge in sciences and engineering. He holds a doctorate in combustion from Ecole Centrale Paris. His doctoral thesis investigated combustion dynamics mechanism identification, prediction, and passive control for swirl-stabilized flames with theoretical, experimental, and numerical methods. He was senior research scientist at the research center of United Technologies Corporation developing passive control strategy and modeling capabilities to support NASA ERA and Pratt and Whitney’s commercial combustors program. He is a reviewer for ASME IGTI, The Proceedings of the Combustion Institute, AIAA SciTech forum, Combustion and Flame, Combustion Science and Technology, and the International Journal of Spray and Combustion Dynamics. He is Senior Member of AIAA and Member of the Propellants and Combustion AIAA Technical Committee. He has been appointed USNC/TAM member and AIAA Professional Society representative.

Chris Caulfield

Chris Caulfield

Chris Caulfield is a Master student in the C-PARC group intent on becoming a Ph. D student. His research focuses on premixed swirling flames and flame stabilization with hydrogen fuel under the guidance of Paul Palies. In May 2021, Chris graduated from Tennessee Technological University with a Bachelor of Science degree in Mechanical Engineering with a Mathematics minor. At TTU he was an active member of Engineers Without Borders and tutored Freshman to junior level engineering courses. Chris enjoys hobbies such as Formula 1, 3D printing, and running.

Tate Prater

Tate Prater

Tate Prater is a first-year graduate student from Chattanooga, Tennessee. In the spring of 2021, he graduated from the University of Tennessee, Knoxville with a bachelor’s degree in aerospace engineering. His current role at the C-PARC group at UTSI includes one-dimensional flame simulations using the Cantera software as well as the study of fuel and air mixing-mechanisms to enable future lean, fully premixed combustion for gas turbine engines. I am grateful and excited to be a part of the C-PARC team where we have the opportunity to work towards clean aviation by greatly reducing the amounts of carbon dioxide and nitrous oxide emitted into the atmosphere. Outside of school, Tate enjoys playing sports, spending time with friends and family, and private piloting.

The increase of computing power -over time has rapidly expanded the roles of DNS as an essential tool to provide insights into the intricate dynamics of the turbulence-chemistry interaction with emphasis on more complexity associated with real fuel effects chemistry and operating conditions approaching those realized in the realistic combustion systems. Nonetheless, the emphasis on realistic geometry has yet to be tackled as most configurations investigated focused on 3D DNS boxes with the periodic domain. My current work discusses a reacting fluid dynamic DNS simulation of a premixed H2/air swirling flame under high swirl atmospheric conditions and develop a computational strategy to compute at DNS resolutions a relevant high-swirl geometrical configuration by including the swirler part itself and solving two of the key flame and turbulence interaction physical scales. Gan Xiao likes running, driving, and cooking in my spare time, and enjoy the life at Tullahoma.

Sadik Rizvi

Sadik Rizvi

Sadik Rizvi has completed his B.S. in Mechanical Engineering from Mumbai University (2014), and M.S. in Mechanical Engineering from Wayne State University (2017). Between 2017 and 2021, I worked in automotive industry at both Caterpillar (2017-2018) and Cummins (2018-current) as a diesel engine test engineer. I will be starting my Ph.D. in Aerospace Engineering at UTSI in summer 2022 at C-PARC under supervision of Prof. Paul Palies. My Ph.D. research interest includes flame speed characterization for premixed H2-air swirled flame, code/algorithm development for static and dynamic component for non-reacting and reacting flow.

Hugo de Nercy Maingard

Hugo de Nercy-Maingard

My name is Hugo de Nercy-Maingard and I am a French student in engineering school. I studied aeronautical engineering for 5 years at ESTACA and specialized in engine and energy system integration. In addition, I will do a specialized master’s degree at SUPAERO next year in order to learn even more about aerospace propulsion. I did several internships during my studies, particularly in the field of aircraft maintenance, at Air France and VallJet (French business airline). This year, I am joining UTSI as part of my engineering end-of-study internship. During these 6 months, I will work on the hydrogen-powered aircraft, in particular on its fuel system, from tank to combustor injector. The objective of my mission is to conduct research on this subject in order to offer solutions to retrofit a subsonic commercial aircraft such as the A320.
