| Abstract | The reliable prediction of the acoustic emission of a fan is still computationally extremely expensive. Therefore, to achieve the low noise target a substantial skew of the rotor blades and a combination of the counts of blade and guide vanes for minimizing mode propagation in the duct system are chosen. Naive blade skew can introduce 3D-flow effects with a substantial degradation of efficiency. Therefore, the rotor blade shape and the guide vanes are optimized aerodynamically via an automated CFD-RANS-based optimization scheme. |
