Numerical Simulation on Dynamic Characteristics of a Extra-high Pressure Pneumatic Blowing Valve

Abstract

Abstract:

An extra-high pressure pneumatic blowing valve was analyzed and a mathematical model for the valve was established based on real gas equation of state. The effects of structural parameters and boundary conditions on dynamic characteristics of the valve was studied by simulation. The results of the paper is very helpful for the optimization design of the valve．
