Resonant Amplitudes of Pressure Pulsation in Pipelines : 2nd Report, A Calculation by Method of Transfer Matrix

Abstract

A method is proposed to calculate the resonant amplitudes of pressure pulsation in pipelines by using transfer matrices in which equivalently linearized damping forces are employed. The resonant curves for several pipelines with an orifice, a tank or a branching are calculated. The results show good agreement with the experimental values. The pressure amplitudes for the 2nd harmonic component which arise from the piston-crank mechanism are calculated and are superposed on ones for the fundamental component. The results also show good agreement with the experimental values.
