Abstract
A new parallel computational technique has been proposed for the liquid flows including granular mixture with multi-block grid system. In this technique, a three-dimensional computational volume is decomposed into multiple blocks which are represented by 3D body-fitted coordinates. Both of the computations of particle motions with the distinct element method (DEM) and liquid flows with a turbulence model in the multiple blocks are executed simultaneously. The interaction between two phases are take into account on the basis of a two-way method. Since the numerical visualization procedure is also treated as one of the parallel processes, it scarcely affects the efficiency of the other computations. The computational method was applied to the granular binary mixture exposed to the oscillating flows in a pipe. As a result, it was shown that the reasonable transportation of particles is predicted and that the segregation of the granular mixture is qualitatively predicted.
