Abstract: Recent improvements in computational methods and availability of high-performance computing allows for solving wide range of problems using direct numerical simulation (DNS) and interface tracking method (ITM) approaches. Those capabilities also create opportunities in new methods of big data analysis of complex flow phenomena. This presentation overviews recent progress in simulation, data analysis and model development of multiphase bubbly flow in my research group. In particular, ITM of multiple bubbles in channel and reactor subchannel geometries will be presented, as well as single bubble controlled simulations for interfacial forces estimation. Some results from in-situ visualization and simulation steering capabilities will be shown.
Biographical Sketch:Dr. Igor Bolotnov is an Assistant Professor in Nuclear Engineering Department at NC State. He got his Bachelors in 2002 in Applied Math from Bashkir State University (Ufa, Russia) and went on to get M.S. (2003) and Ph.D. (2008) in Engineering Physics from Rensselaer Polytechnic Institute (Troy, NY). After post-doctoral experience at RPI he started at his present job in 2011. Dr. Bolotnov research is focused on fundamental studies of multiphase flow turbulence with applications to nuclear reactor geometries and conditions. Microscale modeling, high fidelity simulations and large scale data analysis is the primary efforts in his group. He holds a joint appointment with Oak Ridge National Lab through DOE’s Energy Innovation Hub, CASL.
