The Immersed Boundary Method

Speaker: Charles S. Peskin, New York University

Location: Warren Weaver Hall 1302

The immersed boundary (IB) method is a framework for the mathematical formulation and numerical solution of problems involving fluid-structure interaction.  The method separates the fluid representation from that of the structure so that each can be described in its most natural way.  The two representations are then linked by a regularized Dirac delta function that is used in the application of force by the structure to the fluid, and in the evaluation of fluid velocity at the location of the structure. Applications include the heart, red blood cells, bacterial flagella, osmotic swelling, molecular motors in fluid, and the helical descent of maple seeds.
