Bio-sketch

Dr. Vivek Kumar is currently an Assistant Professor in Department of Mechanical Engineering at Netaji Subhas Institute of Technology (NSUT), Delhi. Previously, Dr. Kumar had served as Assistant Professor in Department of Mechanical Engineering, Pandit Deendayal Energy University Gandhinagar, Gujarat (2019-2021) and Galgotias University (2013-2015). He received his B.E. in Mechanical Engineering from C.R State college of Engineering Murthal, Sonipat. He had also worked as Design Engineer in Machine Building (MBD) of ISGEC Yamunanagar from 2007 to 2010. There his primary responsibilities were design of transmission system and structural frame of Mechanical presses. He did Masters in Design of Mechanical Equipment from Mechanical Engineering Department at Indian Institute of Technology (IIT) Delhi in 2013. He received his Ph.D. in Mechanical Engineering from Indian Institute of Technology Roorkee in 2019. He has also assisted his Ph.D. supervisor in various sponsored/consultancy projects collaborated between IIT Roorkee and state agencies such as BHEL Haridwar, RDSO Lucknow etc. Dr. Kumar’s research is focus on modeling and advanced simulations of fluid film bearings, non-Newtonian lubricants and smart lubricants. Recent thrusts have centered on application of smart lubricants, bionic and textured surfaces in fluid film bearings. His research works draw heavily on expertise in simulation of fluid film bearing, smart lubricants and structures, structure-property relationships in fluid flows, numerical techniques for highly non-linear systems. Dr. Kumar has been regularly publishing research articles in peer reviewed journals of international repute.
