Optimization of fan noise by coupling 3D inverse design and automatic optimizer

Fan Noise 2012, Senlis (France)

In many electronic cooling applications there is in increasing demand for high pressure rise compact axial fan design. This can only be achieved by increasing fan rpm, which can result in higher noise. In this paper a methodology is presented based on coupling a 3D inverse design method together with Design of Experiments, Response Surface Modeling and Multi-Objective Genetic algorithms in order to improve the efficiency and tonal noise from high rpm cooling fans.
