| 摘 要： | 建立了超音速汽液两相流激波过程的数学模型,得到了激波前后的流动关系,并对激波后的流动规律进行了初步分析,建立了两相扩压段的优化模型。研究结果表明,在激波后,流体压力上升,速度下降,与单相气体的正激波特性相似;其对应的音速与汽液两相流体的空泡率、压力及液相密度等因素有关。

| Abstract: | The mathematical model was developed to illustrate the supersonic steam-water two-phase flow shock wave. The relationships between the states before and after the shock wave was obtained, the primary analysis has been done to show the flow mechanism and a optimization model has been studied based on the variant functional theory. According to the present work, the pressure of the fluid and the velocity decrease while across the shock wave, which is similar to that of the single compressible gas. Then the corresponding sonic velocity of the two-phase flow is determined by the void ratio, pressure and density of the liquid phase. |
