Flow Field Analysis and Structure Optimization of Water Hydraulic Poppet Valve Based on the CFD

Abstract:

This paper builds two water hydraulic poppet valve models which are of different structure, and simulation analysis used by FLUENT software on it’s internal flow field. The analysis results show that, after improving the structure of water hydraulic poppet valve, import and export pressure value differences decreased, effectively restrains the generation of cavitation, reduces the vibration amplitude and turn down noise, reduces loss of turbulent energy, the overall performance is superior to the traditional structure.
