A novel approach to numerically estimating the acoustic power produced by gas flow through control devices is presented.
The procedure is based on the simulation of stationary fluid flow by means of the Reynolds Averaged Navier-Stokes (RANS) equations
employing Computational Fluid Dynamics (CFD) techniques. An appropriate expression for the acoustic power density as defined by
existing literature allows to obtain the acoustic power by integrating over an aptly-defined source region. A discussion of the results
obtained for a single-hole orifice plate through the proposed and the reference international standards’ procedure follows
