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 |
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.
