Abstract
A research on dynamic characteristics of a pipeline pulsation damper is presented in this paper. The study covers an investigation of acoustic wave propagation in a pipeline numerical model. For this purpose, the numerical model which was previously obtained for estimation of hydrodynamic noise after the damper diffuser has been verified. The verification is conducted using URANS model. The simulation results illustrate the adequacy of the present model in calculating acoustic wave propagation. Hence, the acoustic characteristics obtained in further calculations can be regarded as reliable. The numerical results demonstrate that an initially plane acoustic wave does not change its form and the overall amplitude level of acoustic oscillations varies in accordance with changes in the geometry flow cross-section.
