| 摘 要： | 本文结合液滴成核、生长理论及Ｅｕｌｅｒ方程组，在无滑移假设下，导出了描述存在自发凝结的湿蒸汽两相流动控制方程组。对汽液两相流动控制方程组采用ＴＶＤ格式离散、时间推进法求解。对准一维喷管中的湿蒸汽两相流动进行了数值模拟，得到了满意的计算结果。

| Abstract: | A model has been developed for the calculation of wet steam flows with spontaneous condensation under the hypothesis of inter-phase zero speed slip. It describes the nucleation and subsequently droplets growth coupling to the Euler equations for dry steam. The TVD scheme is adopted and the time-marching technique is implemented. A numerical simulation for a 1-D nozzle has been performed and the pressure distribution along the nozzle exis agrees well with that of the experiment. |
