Dr. Gautam Choubey is presently working as an Assistant Professor in the Department of Mechanical Engineering at the National Institute of Technology (NIT) Silchar Assam, India. Before joining NIT Silchar, he worked as an Assistant Professor in the Department of Mechanical and Aerospace Engineering at IITRAM, Ahmedabad (An Autonomous Govt. University), India from December 2019 to December 2023, as a senior assistant professor in the Mechanical Engineering Department at MITS-UGC Autonomous Institute, Andhra Pradesh, from October 2018 to November 2019, and as a temporary faculty, at NIT Silchar, from July 2017 to June 2018. He holds a Ph.D. in the field of supersonic combustion, an M.Tech in Thermal Engineering from the National Institute of Technology Silchar, Assam, India. He is working past 10 years on Computational Fluid Dynamics (CFD) modelling of supersonic compressible flow and authored over 50 publications in reputed journals (SCI/SCIE). His research interests mainly include scramjet combustion, supersonic combustion, turbulence modelling in high-speed flows, and shock-boundary layer interaction. Dr. Choubey’s name also figured among the top 2% researchers and scientists of the world in a report published by Stanford University, USA and Elsevier BV, Netherlands for the year 2023, 2022, and 2021. Dr. Sumit Tripathi is currently working as an assistant professor in the Department of Mechanical and Aerospace Engineering at the Institute of Infrastructure, Technology Research and Management (IITRAM), Ahmedabad. He earned his Ph.D. jointly from IIT Bombay (India) and Monash University (Australia) in 2017. He has worked as a postdoctoral fellow at Monash University Australia during 2017–18, and as an Institute postdoctoral fellow at IIT Kanpur in 2019. He has more than eight years of experience in industry and academia. He has authored several papers in international journals, book chapters, and conference proceedings and has presented oral talks in conferences across India, Australia, Japan, and the USA. He is a life member of NSFMFP, ISHMT, IPA, ISTAM, ISTE, and SSME. His research interests include experimental and computational fluid dynamics, rheology of complex fluids, adsorption kinetics, and interfacial science. V. K. Singh is currently working as a scientist/engineer at Thermal Engineering Division of Space Applications Center, ISRO, Ahmedabad, India. He is working in the area of thermal design, analysis, and testing of spacecraft payloads. He worked at Propulsion Research & Studies Entity of Liquid Propulsion Systems Center, ISRO, Trivandrum, from the year 2007 till 2013, where he worked mainly in CFD analyses for engine/stage components and electric propulsion systems. He has research interests in heat transportation systems, phase change materials, Cryogenic, etc. He has published papers in several international journals and conference proceedings. He worked as a project manager (Thermal) for various payloads of ISRO like RISAT-2B, GSAT 20, 24, IDRSS, etc. He is the recipient of Dr. Wille Memorial Prize for the year 2007, conferred by the National Society of Fluid Mechanics & Fluid Power, India.
