- Abstract
In this paper, mechanism oi interaction between shock wave and particles is investigated using CFD-DEM model. In CFD-DEM model, the limit o i the grid resolution depends on the particle size. The particle-grid is introduced to solve this problem, and investigate the effect o i it in the gas-particle shock tube. From the result o i no particle grid case, large pressure oscillations appear because the grid size is almost the same as the particle size. On the other hand, the results of pressure fluctuations are good agreement with the experiment results using particle-grid. Hence, the particle-grid contributes to maintain calculation accuracy.
