  • 1108 Reduction of Aerodynamic Noise Occurring Around the Valve in Exhaust System

抄録

This study deals with the aerodynamic noise generated from a valve in an exhaust system. Because of the aerodynamic noise, noise reduction effect of actual exhaust system is less than a theoretical valve. The aerodynamic noise from the valve, generated for the condition of valve and flow velocity distribution in order to find the relations of flow velocity distribution and aerodynamic noise generated from the valve, valve set angle and valve mounting position changed. The result shows that the flow velocity distribution and valve mounting position have the effect of noise reduction.
