The impact of geometrical parameters on hydrodynamic noise generation

摘要

Measurement of the acoustical characteristics of throttling valves, particularly in water installation systems, is usually based on airborne measurements. However, direct measuremetns of fluid-borne noise give us a better understanding of noise-source acoustical characteristics. This method allows us to use the determined noise-source characteristics to create hydroacoustical models describing the relationship between hydraulic and acoustic conditions. This method also show the influence of geometrical parameters on noise production and emission.
