Analysis on motion behavior of spherical shell in a periodical shear flow based on cuda parallel computing technique

Abstract

The three-dimensional numerical parametrical study for movement of spherical shell in annular boundary with the effect of particle medium shear flow is researched based on GPU (Graphic Processing Unit) parallel computing. The method of three-dimensional periodic boundary is presented and reliability demonstration for results of numerical simulation is carried out through a quarter of annular periodic boundary. With the object-oriented programming approach, CUDA is applied to improve calculation efficiency. The results show that the algorithm of three-dimensional periodical boundary is feasible and effectually to enhance computational efficiency. With specific parameters, spherical shell can emerge on surface of particle medium due to shear flow.
