Computing Fluid Flow with Moving Interfaces - Two Examples
Speaker: Jin Wang
Dr. Jin Wang is Associate Professor of Mathematics at Old Dominion University.
His research interests include numerical analysis, computational fluid dynamics, and
mathematical biology. More details of his research can be found at his home page:
Fluid flows with moving interfaces occur in a wide range of natural and technological
phenomena, yet our understanding of the fundamental mechanism involved remains limited
at present due to the strong nonlinearity and the multiphysics inherent in these processes.
In this talk, we will present two examples related to such applications: one for the study of viscous effects on the interfacial motion between two slightly viscous fluids (a two-phase flow problem), and the other for the simulation of a large number of solid fibers sedimenting in Navier-Stokes flow
(a fluid-structure interaction problem). We will focus on the computational aspects in studying these problems, with some mathematical analysis to augment the computation when applicable. We will discuss both numerics and some interesting physics revealed from simulation.
