摘要
基于颗粒轨道模型,采用二元碰撞假设,在二维拉氏流体动力学程序上实现了气-粒两相混合程序的研制。使用气-粒两相混合程序对不同充气压力条件下的微喷混合问题进行了数值模拟,给出了喷射场随时间演化过程,计算结果与实验定性一致。
Based on the Particle trajectory model, the program of two-phase mixture of gas-particle was developed with two-dimensional lagrange hydrodynamic program. The problems on shock induced matter ejection into gas in different initial pressure were simulated, and the process about the ejecta head position versus time was given. The simulation results are consistent with the experiment in qualitative.
