Abstract:
In order to learn the transient flow field and dynamic characteristics of peessure re． ducing valve during start—up process，a 2-D mathematical model for a large flux pressure reducing valve(PRV)is established and the dynamic mesh and fluid-solid coupling simulation technique is developed in this paper．The internal flow field and the movement of the valve core is coupled．The transient flow field of startup process is simulated．Based on the simulation the dynamic characteristics of the PRV are studied through inspecting the parameters of diffrernt positions．
