EAA Benchmark for an axial fan

Research output: Contribution to conferenceAbstract


We present detailed numerical results of the EAA benchmark case of an axial fan. Thereby, we aim to present the whole aeroacoustic simulation process for a successful computation of the flow and acoustic signature of an axial fan: (1) Meshing approach for the CFD simulation; (2) Turbulence modeling; (3) CFD convergence study; (4) Evaluation of the most significant flow results for a subsequent acoustic simulation; (5) Computational domain and meshing for the simulation of the acoustic field; (6) Acoustic source term evaluation, possible truncation and interpolation from the CFD to the acoustic grid; (7) Acoustic field computation and evaluation of its most relevant physical quantities. For the hybrid aeroacoustic computation we apply a detached eddy simulation (DES) to model the turbulent flow and the perturbed convective wave equation for the computation of the radiated sound.
