Mathematical challenges in cardiovascular applications

Thursday, April 24, 2014 at 3:30p.m.
Suncica Canic (University of Houston)
Abstract: Mathematical modeling and numerical simulation have been recognized as important tools for understanding of the human cardiovascular physiology and pathophysiology, as well as cardiovascular treatment design. On the course of the development mathematical models for various cardiovascular applications, novel mathematical and computational problems arise. In this talk we will discuss a couple of such examples. One is the development of new mathematical methods for the study of existence and numerical simulation of solutions to fluid-structure interaction (FSI) problems between blood flow and multi-layered vascular tissue. The second one is modeling of the mechanical properties of cardiovascular devices called stents, by using a novel approach based on dimension reduction, leading to the mathematical concept of “hyperbolic nets”. The speaker will present an overview of the literature on mathematical analysis and numerical simulation of FSI problems in hemodynamics. A new, partitioned (modular) numerical scheme will be introduced, and the main steps of the convergence/existence proof will be outlined. This scheme is the first FSI scheme for fluid-composite structure interaction problems, which is particularly useful for the simulation of FSI problems with multi-layered structure of arterial walls, FSI involving heart valves, and FSI between blood flow, vascular tissue, and endovascular stents. Our numerical ...
