A numerical analysis for silencers of the multi hole orifice valve has been performed. The Reynolds-Averaged Navier-Stokes equations with K-ε turbulence model were employed to compute steady. incompressible flow, an symmetric computational domain. and unstructured grids. The resolution of flow field is observed by pressure distribution, flow streamline, valve flow coefficient and valve loss coefficient. The valve flow coefficient reduce approximately 9% but valve loss coefficient increse approximately 16%.
