Numerical Analysis for a Simple Shape Silencer for Intensity Diminution of High Pressure Blast Flow Fields
고압 폭발 유동장의 강도 감소를 위한 간단한 형상의 소음기에 대한 수치해석
Abstract
A numerical analysis was made to investigate the intensity diminution of a simple silencer for high pressure blast flow fields. Reynolds-Averaged Wavier-Stokes equations were solved for an axisymmetric computational domain constructed by multi block Chimera grids. A blast flow field without the silencer was also calculated to validate the present numerical method. The evolution of high pressure blast flow fields was observed by depicting calculated contours of pressure and Mach number. It was found that the tested silencer could achieve 76 percent intensity diminution.
