2350 軸対称音速噴流中の凝縮に関する研究(S46-5 圧縮性流れの基礎と応用(混相流),S46 圧縮性流れの基礎と応用)  [in Japanese] 2350 A Study of Condensation in Axisymmetric Sonic Jet  [in Japanese]

In the present study, a computational fluid dynamics method has been applied to investigate the effects of initial degree of supersaturation at reservoir condition on under-expanded sonic jet structures, such as Mach disk location and diameter, barrel shock wave and jet boundary. The axisymmetric nozzle geometry investigated was a contoured converging nozzle with straight part. As a result, it was found that the characteristics of flow with occurrence of non-equilibrium condensation in the jet were different from those without condensation.
