Title:

Numerical Computation of Periodic Stokes Flow


Abstract:

Some microorganisms swim by having tiny hairs on their surface, so-called cilia (Latin for eyelash), perform a coordinated motion, similar to rowing. This repeated pattern gives rise to periodic Stokes flow. Independent of the actual application, the goal now becomes to design fast numerical methods that exploit periodicity. We present two completely different approaches. The first one makes use of the Fourier transform and is really fast. The second one is surprisingly naive, yet outperforms the first one in some settings. We merge the best of both methods in a grand finale.
