Title:

Generalized immersed boundary method applied to mathematical modeling in biology


Abstract:

A generalized version of the immersed boundary (IB) method combined with the unconstrained Kirchhoff rod theory has been developed to study biological fluid mechanics in the filamentous structure such as bacterial flagella and DNA strand.
 
A thin elastic filament (rod) in the Kirchhoff model that resists bending and twisting can be modeled as a "three-dimensional space curve'' together with an orthonormal triad (material frame) at each point of the rod. The triad indicates how much the filament bends or twists. This is a well-established theory in the statics and dynamics of thin elastic filaments without fluid. Combining Kirchhoff rod theory with the standard models of viscous incompressible fluids will allow us to study the complicated hydrodynamics of bacterial swimming or DNA supercoiling.
