Resonant Amplitudes of Pressure Pulsation in Pipelines : 1st Report, Resonant Amplitudes in Case of a Single Sinusoidal Flow Input

Abstract

A method is proposed to calculate resonant amplitudes of pressure pulsation in the pipelines connected to reciprocating compressor delivery systems, in which nonlinear damping forces proportional to the square of velocity are used and the energy balance between excitation and dissipation are taken into consideration. Calculated values are compared with experimental values. As the result, it is confirmed that by the method proposed here resonant pressure amplitudes are estimated with sufficient accuracy for practice in case of a single sinusoidal flow input.
