Numerical analysis of fluid flow in the throttle poppet valve channel in precision machinery

Abstract

The velocity, pressure, stream function and velocity magnitude in different case are discussed by numerical analysis and simulation of the fluid flow in the throttle poppet valve channel in Precision Machinery. The place and intensity of vortexes are analyzed and the main causations of energy loss are found. It is indicated that the stream function, velocity magnitude, energy loss and flow noise is reduced, negative pressure is changed and the use of energy is improved by optimizing design of the throttle poppet valve spool.
