Dr. Vineet Kumar is an Associate R&D staff in the Thermal Hydraulics group within NEFCD at Oak Ridge National Laboratory (ORNL). Vineet received his PhD (2019) in nuclear engineering at the University of Illinois Urbana-Champaign, and his MS (2012) in mechanical engineering at Purdue University. He has over 8 years academic and industrial experience in thermal-hydraulics system modeling, multi-phase flows experimentation and modeling, and computational fluid dynamics. At ORNL, Vineet has supported various projects such as the Proton Power Upgrade (PPU) project at the Spallation Neutron Source, the NEAMS project on improving BWR modeling in CTF – the thermal hydraulics code in the VERA suite, as well as NEUP, and HPC for manufacturing projects. Vineet is currently working on time-at-temperature analysis in CTF for the NEAMS program, a HPC4Mfg project on secondary lead smelting, and on Modelica-based system model development for datacenter cooling amongst others.
