固気混相流の熱流動解析のための DEM+LBM ハイブリッドモデルの開発

抄録

A hybrid model of Discrete Element Method (DEM) and Lattice Boltzmann Model (LBM) to analyse the heat and mass transfer for solid-gas two phase flow is explained and some results of numerical simulation by this model were shown in this paper. Since the particles flow is complicated, the physical phenomena is difficult to understand and the details of the flow cannot be observed. Therefore, numerical simulation is one of the significant approaches which solve the problem in regard to particles flows. The hybrid model of DEM and LBM is adapted to the recent high performance parallel computer systems. Hence, this model can be one of the powerful tools to illustrate and reveal the physics of particulate flows.
