December 1	Keynote  09:30		Vivek V. Buwa (IIT Delhi) High-Performance Computations of Particle-Resolved Multiphase Flows Abstract: Multiphase flow processes are widely used is several technologically and commercially important processes in power generation (e.g. coal based electricity generation), clean coal technologies, nuclear power generation, upstream oil and gas industry, oil refining, petrochemical and chemical process industry, mineral processing and metallurgical industries and so on. High-performance computing has offered enormous possibilities in simulations of particle-/interface-resolved multiphase flows. This has significantly helped to improve our understanding of complex multiphase flows and also to develop models (based on continuum and discrete particle approaches) to simulate industrial multiphase flow processes. In the present talk, particle-resolved CFD simulations of fluid flow, heat and chemical reactions will be presented and it will be shown how the HPC has made it possible to optimize shapes of the catalyst particles/structures for different reaction systems or to simulate catalyst deactivation due to coking. Further, with the help of the pore-resolved simulations of liquid flow in packed beds and two-phase oil-water flow in porous media, it will be shown how the HPC simulations can help to understand the pore-scale flow processes, effects of surface tension and wettability on the pore-scale flow process. Bio: Vivek is a professor at IIT Delhi. He obtained doctorate from IIT Bombay. His research interests include computational flow modeling and simulation, single/multiphase flows, multiphase reactor engineering, and transport phenomena and reactions in multiphase systems. He is a recipient of research fellowship from Alexander von Humboldt Foundation Germany, Young Engineer Award from INAE, and Outstanding Young Faculty Fellowship from IIT Delhi. He has also won the Teaching Excellence Award at the institute.
