Computation of Swimming Motions Using Regularized Stokeslets
Colloquium| Speaker: | Ricardo Cortez, Tulane University |
| Location: | 693 Kerr |
| Start time: | Tue, Apr 23 2002, 4:10PM |
Description
The fluid motion surrounding swimming microorganisms is often
modeled using the Stokes equations of fluid flow due to the small
length scales. I will present a numerical method for computing
Stokes flows interacting with immersed flexible bodies or moving
through obstacles. The method treats the flexible bodies as sources
of force in the Stokes equations. The velocity is the superposition
of flows due to each of the force elements. Exact flows are derived
for forces that are smooth but supported in small spheres, rather
than point forces. I will explain the idea of the method, the
connection to the standard fundamental solution of the Stokes
equations, and I will present several examples in two and three
dimensions related to flagellar motions.
