Governing Equations of Blood Flow and Respective Numerical Methods
Coronary heart disease which is a major cause of heart failure in the United States has a focal nature which is due to local hemodynamic disturbances. The computational fluid dynamics (CFD) method has become a powerful approach to understand blood flows in the cardiovascular system and its local features. This chapter outlines the field equations for blood flow and some of the approaches for numerical solutions. Specifically, the text focuses on the finite difference (FD) and finite element (FE) methods with applications to blood flow dynamics in coronary arteries.
