Special Session: To Celebrate Prof. Sankaran Sundaresan's Career Long Accomplishments

Professor Sankaran Sundaresan has dedicated his career to education and scientific research in multiphase flows. Except for early research in flow phenomena in trickle bed reactors, Professor Sundaresan has concentrated on the nature and simulation of fluid-particle systems. Specifically, he has focused on computational fluid dynamics simulations aimed at understanding the origin and behavior of meso-scale structures in gas-solid flows. From this work, the concept of the coarse-grained, or filtered, two-fluid model was developed. The filtered model consists of the averaged two-fluid equations with closures developed through detailed computational experiments that resolve meso-scale flow behavior. The closures are, essentially, sub-grid-scale models that account for meso-scale flow structures and their behavior without the need to resolve either. This methodology has made possible accurate and timely industrial-scale simulations of gas-solid flows. More recently, Professor Sundaresan has focused on particle-based simulations as a means of developing similar sub-model closures for more complex physical phenomena occurring in granular flow such as friction dominated flow and the fluidization of wet or cohesive material. To celebrate his career accomplishments, this session will provide papers that demonstrate Professor Sundresan’s legacy in the application of computational fluid dynamics in two-phase flows.
