Dr. Bolotnov holds a joint faculty appointment with Oak Ridge National Laboratory and actively collaborates with Nuclear Energy and Fuel Cycles Division. He teaches reactor engineering (NE-402/502) and multiscale simulation of two-phase flow (MAE/NE-577) courses.
Dr. Bolotnov specializes in computational fluid dynamics applications in nuclear reactor engineering in general, and in multiphase turbulent flow. Dr. Bolotnov research has been supported by the Department of Energy’s Consortium for Advanced Simulation of LWRs (CASL), the U.S. Nuclear Regulatory Commission, DOE’s NEUP program, and the National Science Foundation (NSF) among others. Bolotnov’s Multiphase research group has vast experience and capability with high-performance-computing enabled CFD simulation of complex single- and multi-phase flow, using PHASTA code.
Dr. Bolotnov is currently serving as Secretary for the Thermal Hydraulics Division of American Nuclear Society (ANS). In addition, he has been appointed the Associate Editor for Annals of Nuclear Energy.
