Abstract

This paper describes the application of a three dimensional Computational Aeroacoustics (CAA) methodology to the prediction of jet noise. The technique has been implemented using parallel computers. In this approach the non-linear disturbance equations are solved in a conservative form using a finite-difference based technique. A fourth order optimized Dispersion Relation Preserving (DRP) scheme is used for spatial discretization and a fourth order classical Runge-Kutta scheme is employed for temporal discretization. The three-dimensional CAA code has been parallelized on the IBM-SP2 parallel computer using Message Passing Library (MPL) routines and a domain decomposition strategy. Excellent parallel performance has been obtained using the present code. Acoustic results are presented for a perfectly expanded supersonic axisymmetric jet case under harmonic and random inlet conditions. Results are given for both the instantaneous and averaged flow and acoustic variables. Comparisons are made between the predictions and experimental data.
