Investigation of Coupling and Interacting between the Condensation Shock and Aerodynamic Shock in the Supersonic Non-Equilibrium Steam Flow

摘要：

The supersonic non-equilibrium steam flow with spontaneous condensation and condensation shock was numerically studied based on the computational fluid dynamics method. A conservative compressible numerical model coupling with non-isothermal classical nucleation model was developed and used to predict the spontaneous condensation phenomenon with homogenous nucleation in supersonic steam flow. The improved high resolution Roe-FDS scheme was used to capture the transient characteristics of the condensation shock and the aerodynamic shock in the supersonic turbulent flow. Based on the simulation, the process of formation of the condensation shock was revealed, and the coupling and interacting between the condensation shock and aerodynamic shock were investigated, hi the study, the difference between the condensation shock and the aerodynamic shock was investigated, and the influence of the aerodynamic shock on the non-equilibrium phase change and condensation shock was revealed. In addition, the counteraction of the homogenous condensation on the aerodynamic shock was also studied.
