Sara Pålsson: Simulating bubbles: a boundary integral approach for Stokes flow

This talk is about bubbles and drops, and how to simulate them using boundary integral methods. With this kind of methods we can compute the deformation of bubbles using only a discretisation on the fluid-bubble interfaces. We will describe our method for two-dimensional Stokes flow and display some results. Furthermore, we will show that in certain cases, complex analysis can be used to obtain analytical descriptions of the flow — which provides execellent validation opportunities.
