| 摘 要： | 建立二维轴对称气固两相双流体物理模型.对三种不同源区初始质量比内能E0/10、E0/100、E0/1 000,固体堆积颗粒作用下气相流场能量、压力衰减进行数值模拟.结果表明:初始质量比内能越高,堆积颗粒作用下流场动能、内能衰减越快;初始质量比内能越高,流场压力衰减达到准静状态的速度越快,准静态后压力衰减也越快.

| Abstract: | Two-dimensional axi-symmetric gas-solid two-fluid model was established. Under three conditions of source: E0/10,E0/100,E0/1 000 (initial energy per mass of gas),diminishing of gas energy and gas pressure caused by packing particles was studied. It shows that: With higher initial energy per mass of source kinetic and internal energy of gas is diminished by packing particles more quickly,gas fluid is close to stillness more quickly,gas pressure is decreased more quickly. |

| Keywords: | high temperature and high pressure two fluid model packing particles energy attenuation |
