VOCAL-FAN · VIRTUAL OPTIMIZATION CFD PLATFORM ALLOWING FAN NOISE REDUCTION

The activities encompassed by this proposal consist in the development and exploitation of a methodological approach, suitable for the optimization of the fan and duct geometries in an electrical machine, with the aim to improve both the aerodynamic and acoustical performance of the system.The global activity will consist in a first baseline CFD calculation, a screening of different fan designs and finally an optimized fan design in terms of fluid dynamic performance and noise reduction.The advanced character of the forecast approach is linked to the following aspects:a) the implementation of the most advanced algorithms and procedures for CFD simulation
