Fluid-Structure Interaction by the Immersed Boundary Method

Speaker: Charles Peskin

Location: Warren Weaver Hall 1302

Date: Friday, October 9, 2015, 1 p.m.


An example of an immersed boundary is a heart valve leaflet. These thin membranes are immersed in blood and move at the local fluid velocity while they simultaneously apply forces to the surrounding fluid that prevent backflow when the valve is closed, and shear the forward flow when the valve is open to create vortices that subsequently promote efficient valve closure. The immersed boundary (IB) method was created to deal with this problem, and has since grown into a generally useful tool for the computer simulation of fluid-structure interaction, especially in biology.

In this talk I'll introduce the IB method in the context of the heart, and then show movies that illustrate various ways in which the IB method has been generalized and applied.
