Spectrally accurate Ewald summation for the Yukawa potential in two dimensions
Sara Pålsson, Anna-Karin Tornberg
An Ewald decomposition of the two-dimensional Yukawa potential and its derivative is presented for both the periodic and the free-space case. These modified Bessel functions of the…

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…

An integral equation method for closely interacting surfactant-covered droplets in wall-confined Stokes flow
Sara Pålsson, Anna-Karin Tornberg
A highly accurate method for simulating surfactant-covered droplets in two-dimensional Stokes flow with solid boundaries is presented. The method handles both periodic channel flow…
