An accurate integral equation method for Stokes flow with piecewise smooth boundaries
Lukas Bystricky, Sara Pålsson, Anna-Karin Tornberg
Two-dimensional Stokes flow through a periodic channel is considered. The channel walls need only be Lipschitz continuous, in other words they are allowed to have corners. Boundary…

Stable and contact-free time stepping for dense rigid particle suspensions
Lukas Bystricky, Sachin Shanbhag, Bryan D. Quaife
We consider suspensions of rigid bodies in a two-dimensional viscous fluid. Even with high-fidelity numerical methods, unphysical contact between particles occurs because of spatia…
