In this study, a numerical model is developed to investigate the fluid and dynamic
characteristics of a direct-operated safety relieve valve (SRV). The CFX code has been used …

In the present study, a cryogenic valve used in launch vehicle liquid propulsion systems is
experimentally and numerically characterized. Two independent measurement campaigns …

The aim of this work is to clarify some issues raised recently on the characterization of the
water hammer, by presenting a numerical analysis on the multiphysics taking place. For this …

We describe the dynamic analysis of a spring-loaded pressure safety valve (PSV) using a
moving mesh technique and transient analysis in computational fluid dynamics (CFD) …

采用流固耦合数值模拟技术研究安溢活门/气罐系统充放气动态特性. 计算中所用流体控制方程

Cryogenic cavitation can be easily encountered in rocket liquid propulsion systems at the
very initial phase of the launch due to the propellant passing through orifices and valves …

Valve systems in rocket propulsion systems and testing facilities are constantly subject to
dynamic events resulting from the timing of valve motion leading to unsteady fluctuations in …

CFD analyses are playing an increasingly important role in identifying and characterizing
flow induced instabilities in rocket engine test facilities and flight systems. In this paper, we …
