A Research on Acoustic Characteristics of Gas Pressure Regulator with Silencer

Abstract

Results of calculations and experimental studies of the acoustic characteristics of the gas pressure regulator with a silencer are reported here. A mathematical model and a method for obtaining a stable solution of the original system of equations was developed. The possibility of reducing the noise of the pressure regulator, when one orifice plate is installed, is presented here. We obtained a good convergence of theoretical and experimental data. The optimization of the flow area silencer consisting of several orifice plates was developed.
