The Finite Volume Particle Method: Toward a Meshless Technique for Biomedical Fluid Dynamics

Popis výsledku v původním jazyce

Very large structural deformations are characteristic of biomechanical fluid-structure interaction (FSI) systems. In heart valves, in particular, leaflet motion is on the order of the scale of the flow domain. Artery walls and red blood cells also undergo relatively large deformations. In this chapter we describe an emerging meshless method, the finite volume particle method (FVPM), which has the potential to solve some of the difficulties of modeling fluid flow with large wall motion and coupled fluid-structure dynamics. The FVPM approach may be understood as a hybrid of smoothed particle hydrodynamics (SPH) and the classical mesh-based finite volume method. It inherits the meshless character of SPH along with the conservation and consistency properties of finite volume methods. The basic concepts of the method are outlined and the extensions required for its practical application to cardiovascular flow are explained. Detailed validation is performed for a benchmark problem of flow coupled with rigid body motion, and a preliminary application to a 2D mechanical heart valve model is presented.
