- Abstract:
- Numerical simulation of flow field through an attitude control system regulator orifice is conducted with FLUENT. Transformation of flow field parameters shows that the flow is restricted,turbulent,impact flow against the wall. The gas flow is pressed against the wall and is rapidly shot out with sonic velocity. There produces shock wave in the compressed flow. Formula for isothermal flow is recommended for great total lose. Because of the existing of shock wave,total pressure varies with gas flowing through regulator orifice. Kinetic equations for steady flow can not be used to explain this process and CFD software is used to analyze this complex turbulent flow field.
