We offer the following reserach topic:
The scope of this master thesis is to investigate aeroacoustic noise emission from the case of a rotating axial fan by modelling the fan as a rotating Embedded Body (EMBB) on a stationary mesh. Scale resolving approaches to simulation of turbulent flow fields e.g., Large-Eddy Simulation (LES), can directly deliver accurate acoustic source terms as input for the following acoustic simulation (AS). The described workflow should be applied with AVL FIRE M, for the LES, where the rotating fan is modelled as an EMBB with openCFS for solving the PCWE. The flow and acoustic results should be analyzed and compared against literature for validation.
The successful completion of the thesis is remunerated with a one-time fee of 3.500,00 EUR before tax.
