An algorithm for coarse particle sedimentation simulation by Stokesian dynamics

摘要：

Coarse Particle sedimentation is studied by using an algorithm with no adjustable parame- ters based on stokesian dynamics. Only inter-particle interactions of hydrodynamic force and gravity are considered. The sedimentation of a simple cubic array of spheres is used to verify the compu- tational results. The scaling and parallelism with OpenMP of the method are presented. Random suspension sedimentation is investigated with Mont Carlo simulation. The computational results are shown in good agreement with experimental fitting at the lower computational cost of O(N ln N).
