Abstract

This article deals with the problem of hydrodynamic noise inside a fluid pressure vibration absorber. The calculation of hydrodynamic noise is based on the results of numerical simulation of fluid flow in the central duct of the vibration absorber. A complete system of hydrodynamics equations is solved with the help of a large eddy simulation turbulence model (LES).
