Title: Stochastic Modeling of Dense Particle Suspensions
Abstract: Disperse two-phase flows are composed of liquid droplets or solid particles suspended in a carrier fluid. Examples of such flows are numerous within engineering and the environment. A timely example is the forthcoming landing of NASA's Perseverance rover on February 18. In this talk, I will explain how the fluid dynamics associated with the exhaust plumes fluidizing the Martian soil can jeopardize missions like these. With this as a motivating example, we will examine the fundamental processes of fluid-particle suspensions, existing theories, and simulation techniques. The focus will be on recent progress in modeling the drag force as a stochastic process that correctly captures fluid-mediated particle-particle interactions.
