Assessment Of CFD Broadband Noise Predictions On A Rod-Airfoil Benchmark Computation

This paper presents a selection of acoustic far field, unsteady aerodynamic and mean flow results obtained from a variety of unsteady codes on a low Mach rod-airfoil test case. These codes are all applicable to complex geometries such as encountered in turbo engines. Therefore the present computations can be regarded as an evaluation of their capability to predict turbomachinery broadband noise. This quite unique benchmarking work of turbomachinery noise prediction tools has mainly been achieved within the framework of the European Project PROBAND, but some of the results where also obtained by an academic cooperation with a Korean partner.
