Fluid Particle Suspension

We develop a fluid-structure interaction (FSI) method based on the ALE method and a dynamic mesh method with an ultimate aim which is to simulate the complicated dynamics of rigid particles in shear flow and to investigate the rheological behavior of the suspension. Because the motion of the fluid and particles in fluid-particle suspension problems is strongly linked, the governing equations are sequentially solved in each solver and the computation is iterated until the solutions converge in a two-way coupling fashion. The mesh system initially designed is deformed or re-meshed in accordance with the moving particles by a dynamic mesh method. Numerical simulation is entirely implemented by our FSI code in the framework of FLUENT. The present simulations have demonstrated the capability of the developed FSI method in simulating the dynamics of single and multiple particles with different arbitrary shapes in shear flows.

Condition Modeling

The objectives of this study are to observe the deformation of mitral leaflet in systole condition and compare the rigidity of heart valve leaflet during systole and diastole conditions. Two-dimensional model of the mitral valve leaflet with ventricle were created using fluid structure interaction model in computational simulations. The result shows rigidity of heart valve leaflet always opposite to degeneration and the simulated displacement models corresponded to normal deformation in physical heart valve in systole condition. Modeling simulation techniques are very useful in the study of degenerative heart valve and the findings would allow us to optimize feature and geometries to reduced deformation of heart valve failure.
