To obtain a low-noise fan design in a justifiable amount of time, efficient computational aeroacoustic (CAA) methods are necessary for the prediction of aerodynamically generated noise. To bridge the gap between the high computational effort of scale resolving simulations and the limited predictability of semi-empirical models, a first principle based approach for broadband noise prediction is developed at the Department of Technical Acoustics of the German Aerospace Center (DLR).
