摘　　要：基于稀颗粒群假定下的双流体简化模型,采用具有高精度、高分辨率的数值方法,研究了粉尘气体中轴对称管口激波绕射诱导的复杂两相流动。得到非平衡两相流动不同于纯气体流动的一些基本物理特征,以及粒子物性参数改变对这些特性的影响。In this paper, based on the simplified two-fluid model under the assumption of dilute gas-particle suspensions, the complex two-phase flow induced by shock diffraction from an open axisymmetrical tube in a dusty gas has been investigated by using high accuracy and high resolution schemes. The basic features of the non-equilibrium two-phase flow which are different from the pure gas, and the effects of changing the physical properties on these features have been obtained.
