Vivek Kumar Singh is currently working as Scientist/Engineer at Thermal Engineering Division of Space Application Centre, ISRO, Ahmedabad. He is working in the area of thermal design, analysis and testing of spacecraft payloads. He worked as Project Manager (Payload Thermal) for various spacecraft payloads (RISAT-2B, GSAT-20, GSAT-24, GSAT-30, IDRSS, etc.) of ISRO. He worked at Propulsion Research& Studies Entity of Liquid Propulsion Systems Centre, ISRO, Trivandrum from year 2007 till 2013, where he worked mainly in the area of CFD analyses for engine/stage components and electric propulsion subsystems. He has research interest in the area satellite payload thermal management, heat transportation devices, PCMs, Cryogenics, etc. He has published papers in peer reviewed international journals. He is the recipient of Dr. Wille Memorial Prize for the year 2007, conferred by the National Society of Fluid Mechanics& Fluid Power, India.

&nb p;Dr. Gautam Choubey is presently working as an Assistant Professor in the Department of Mechanical and Aerospace Engineering at the Institute of Infrastructure Technology Research and Management (IITRAM), Ahmedabad, India. He holds a Ph.D. in the field of supersonic combustion and an M.Tech. in thermal engineering from the National Institute of Technology (NIT) Silchar, India. For the past 8 years, his research has focused on computational fluid dynamics modelling of supersonic compressible flow. Dr. Choubey has authored more than 30 publications in reputed SCI journals. His research interest mainly includes scramjet combustion, supersonic combustion, turbulence modelling in high-speed flows, and shock-boundary layer interaction. He also figured among top 2% researchers and scientists of the world in a report published by Stanford University (United States) and Elsevier BV (Netherlands) for the year 2020. He is also serving as an editorial board member of BMC Research Notes (Springer Nature), Mathematical Problems in Engineering (Hindwai; IF: 1.430).
