Numerical Simulation of the Flow Field inside the Hydraulic Poppet Valve Based on CFD

The hydraulic poppet valve is one of the most important component in the hydraulic transmission and control,whose characteristic of the inner flow filed influences directly the valve's performance.The 3-D geometric model of the poppet valve is established,according to the parameters of the in-service cartridge poppet valve.The hydraulic oil flow inside the poppet valve is simulated,based on the CFD software.In the procedure of the simulation,the adapting mesh is adopted,which is helpful to improve the precision.The study for the valve has offered the significant reference to design the valve and optimize the performance.
