| Outline of Final Research Achievements |
The hybrid numerical model composed of Discrete Element Method (DEM) and Lattice Boltzmann Model (LBM) has been proposed and developed to analyse solid-gas two-phase flows effectively by parallel computers which are driven by many core processors. In addition, athermal LBM for immiscible liquid-gas two-phase flow with large density difference has studied and modified in order to be implemented into DEM-LBM hybrid model and extend this numerical method to the simulation of the granular or powder flows in liquid-gas two-phase flow. Though the calculation method for dispersed phase in DEM adapts to parallel computing, the computation models for continuous phase have some difficulties to fit the parallel computing because of its Eulerian characteristics. The finite difference methods for continuous phase have been replaced by a lattice Boltzmann model which adapt to parallel computing well.
