Abstract

In the present study, an efficient numerical algorithm based on Theoretical methods is developed for the prediction of the noise of aerodynamic flows around two-dimensional geometries. The theoretical formulation for calculating different types of noise is proofed and a solver with a negligible computational cost is developed accordingly. By using the present noise solver, the aeroacoustic characteristics around two test cases are predicted and the obtained results are presented in comparison with the available numerical and experimental data. The present results for noise around NACA0012 and S822 are in excellent agreement with those reported in the literature which shows the accuracy and performance of the present solver based on the theoretical formulation. Employing this quick solver is very crucial to save costs in the preliminary design process of low noise geometries in aerospace engineering. The extension of the present two-dimensional noise solver for the prediction of noise properties around three-dimensional geometries is undergoing.
