| 摘要: |
| 采用粒子仿真方法直接跟踪颗粒相运动轨迹，采用NND格式求解NS方程，数值模拟了气—固两相自由射流流场。计算结果表明，将粒子仿真与CFD方法相结合是研究气—固两相流动问题的有效途径。颗粒相参数变化将对气体流场产生一定影响。 |

| Abstract: |
| With the particle simulation method employed to trace the trajectory of solid particles and NS equation solved with NND scheme, the gas-particle free jets expanding from a high pressure stagnation chamber through a sonic orfice into a quiescent low pressure chamber is numerically simulated. The results demonstrate that combination of particle simulation method with CFD is an effective approach to the two phases problem.The existence of solid particle is of strong effects on gas flow property. |
