Generation and damping of flow oscillations in the region of a joint between a pipeline and a blind branch

Abstract

We consider the problem of self-excitation of oscillations in the pipes of main gas-compressor stations. We present results of model investigations of intense narrow-band oscillations of pressure and velocity in a gas flow, which are due to the occurrence of instability and the formation of a self-oscillating system in the zone of a joint between a pipeline and a blind branch-resonator. The possibility of prevention or attenuation of self-oscillations is indicated.
