Stochastic Simulation of Complex Fluid Flows

Abstract

The PI has developed novel numerical algorithms and computational codes to simulate the Brownian motion of rigid particles immersed in a viscous fluid. This is crucial for modeling flowing colloidal suspensions of passive and active micro and nano particles, which is central to a number of industrial processes and to the design of novel nanofluid materials. The random Brownian motion of particles in fluid can be accounted for in fluid-structure coupling models via the framework of fluctuating hydrodynamics (FHD), which adds a stochastic component to the stress tensor. The PI has developed methods to couple rigid particles to a fluctuating fluid in the framework of the immersed boundary method.
