What is Airfoil Trailing Edge Noise Simulation about?

This paper evaluates a hybrid zonal RANS-LES approach for simulating aerodynamic noise generated by flow past an airfoil trailing edge at high Reynolds numbers. The method utilizes a multi-domain decomposition where acoustic sources are resolved in a LES sub-domain, while the rest is treated with RANS, and the results are compared with experimental data. The study highlights the critical influence of the perturbation model on the accuracy of noise predictions.
