Numerical Simulation for Flow Field of Conical Wing Valve Based on Fluent

In view of the characteristic of severe erosion and cavitation in the high-pressure pipe manifold,according to the actual operating condition,the flow field of the play of it by Fluent software was simulated and computed,Reasons of the erosion and cavitation were promulgated.Some mitigation methods and precautions were proposed.The results of the analysis provided the theoretical supports for the design and optimization.
