Spectral Analysis for Air Flow Over a CavityA procedure has been developed to perform spectral analysis for air flow over a cavity. The air flow is simulated numerically using the commercial CFD software Fluent and the pressure fluctuations are acoustically post-processing using FFT in the mathematical tool Matlab. A parametric study is undertaken that illustrates the importance of achieving a stable and accurate CFD solution in order to obtain reliable noise predictions. Simulation results are compared to experimental data presented at the Computational Aeroacoustics Workshop.
