Finite Difference and Finite Volume Techniques for the Solution of Navier-Stokes Equations in Cardiovascular Fluid Mechanics
The present notes summarize the flow equations involved in cardiovascular-fluid mechanics and the finite difference and finite volume numerical methods that are widely used for the modeling of flow through arteries of large or small size. In the case of flow through large size arteries two numerical methods are presented extensively based on a pressure-correction type methodology and a pseudocompressibility methodology for the solution of steady and unsteady flows through domains of deformable-moving walls. In the case of flow though small size arteries, the level set method is treated for the modeling of the multicomponent flow. Representative flow cases for cardiovascular fluid dynamics are also modeled and solved by using the above methodologies.
