Coupling Internal and External Mechanics of Swimming Organisms: A Computational Approach
Applied Math| Speaker: | Lisa Fauci, Tulane University |
| Location: | 693 Kerr |
| Start time: | Fri, May 10 2002, 4:10PM |
Description
Problems in biological fluid dynamics typically involve the interaction of
an elastic structure with the surrounding fluid. Motile spermatozoa in the
reproductive tract and swimming leeches are examples of such
fluid-structure interactions.
We will describe a computational approach, based upon the immersed
boundary method, that couples internal force-generating mechanisms of
organisms and cells with an external, viscous, incompressible fluid. We
will present recent progress in the modeling of the internal axoneme
mechanics of beating cilia and flagella, as well as 3d undulatory swimming
of nematodes and leeches.
