Abstract:
A method of combining both numerical analysis and experimental research is adopted to analyze the flow field in propellant control valve of the attitude control system. Numerical calculation results are coincident with the experimental data, which indicates the numerical simulation can reliably figure out the characteristics of flow field in the control valve. Analysis of flow field parameter shows the flow striking on valve plug and orifice throttling are the main links inducing flow energy decline, which should be avoided in scheme design. The continuity of passage sections and sufficiency of flowing interspace are also the important links which should be considered in the internal structure design of the control valve.
