Abstract

A hybrid method for a fully coupled determination of aerodynamic sound is introduced. From the instantaneous velocity and vorticity, determined by approximate solutions of the Navier-Stokes equations, acoustic source terms are obtained, which are plugged into the acoustic perturbation equations being solved with a high-order discontinuous Galerkin method. The coupling method is discussed in detail and results of validation tests of the aeroacoustics solver are presented.
