A parallel solver of a splitting approach for Computational Aero-Acoustics (CAA) is presented. The solver is based on a hybrid approach, where the flow field and acoustic fields are computed as separate but coupled processes. The Large Eddy Simulation (LES) based flow solver is parallelized using a domain decomposition approach. The performance of the solver has been evaluated and good parallel performance has been obtained. The acoustical solver utilizes the LES data for computing the acoustical sources. The combined solver has been successfully applied for the computation of the aeroacoustic held in a model gas turbine combustion chamber.
