Igor Bolotnov

Assistant Professor


Dr. Igor A. Bolotnov is an Assistant Professor at North Carolina State University since 2011. His research interested include multiphase flow simulations using interface tracking and CFD approaches, development of new closure laws for multiphase CFD as well as new generation of multiphase turbulent models.

Dr. Bolotnov holds a joint faculty appointment with Oak Ridge National Laboratory. Heis a member of CASL, the DOE-funded energy innovation hub. He is a member of Thermal Hydraulics Methods focus area, where he collaborates with his colleagues from ORNL, LANL, MIT and TAMU to develop a new generation of multiphase boiling flow models based new experimental and direct numerical simulation data.
