英文摘要：

Supersonic non-equilibrium steam flow with spontaneous condensation was numerically studied. Based on the numerical simulation, the non-equilibrium thermodynamic phenomenons such as the homogenous nucleation and the condensation shock were investigated, and the interaction between the aerodynamic compression shock and the homogenous condensation was revealed. The dissipation effect of the shock on the non-equilibrium phase change was discovered and the influence of the shock on the thermodynamic processes of homogenous nucleation, droplet growth on the shock front was revealed.
