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.
