Bio

Vivek M. Rao Ph.D. is a Nuclear CFD Development Engineer in the Thermal Hydraulics Group. With specialized interest in applied fluid mechanics, he has participated in various programs of the U.S. Department of Energy to develop, extend and adapt computational tools on high-performance computing resources to challenges in energy engineering, materials interactions, and large-scale chemical manufacturing processes. Vivek brings 10+ years of inter-disciplinary experience in computational fluid dynamics for reacting flows (gasification, combustion), equipment design (pressure vessel, heat exchangers, turbomachinery), and process intensification. He has participated in experimental investigations relating to synthesis and characterization of nanomaterials for energy storage, surfactant-enhanced soil remediation, and flow visualization.

At ORNL, Vivek has supported mission-aligned research for the Spallation Neutron Source (SNS), Building Technologies Research & Integration Center, and the Material Plasma Exposure eXperiment (MPEX).
