Professor Vladimir B. Khabensky is the leading scholar in the field of heat transfer and hydrodynamics of the single- and double-phase flows in thermal and nuclear power engineering. He has been celebrated for his contribution to mathematical modeling of nonstationary thermo-hydraulic processes in NPP. More recently, he has contributed greatly to understanding of physicochemical and thermo-hydraulic processes in the high-temperature molten corium in the context of the problem of NPP safety during a severe accident involving the core meltdown. He has authored over 160 research manuscripts and inventions. Professor Vladimir A. Gerliga is renowned for his contribution to the field of nuclear power plant safety, hydraulic gas dynamics, pumps, turbines, and power installations of space vehicles. His research focused on physical and mathematical models of thermo-acoustic fluctuations in the channel core of nuclear power plants and designing methods for instability prediction in the main circuit on natural circulation by the analysis of noise. He has authored 5 books and over 150 research manuscripts.
