Topic: Microscale flows around a sphere under random forcing or minimal microorganism models

Abstract: In this talk, I will discuss microscale flows around a sphere under random forcing or minimal microorganism models. First, I will introduce a model that describes the dynamical behavior of small spherical particles immersed in a viscous fluid under the influence of thermal fluctuations. We perform theoretical and numerical analyses of particle diffusion to characterize their motion across varying particle sizes. Second, using the same framework, I will present a minimal model for swimmers and discuss some preliminary results.
