Low pressure axial flow fan with circumferential skewed rotors was studied.The rotors include the traditional radial rotor
the forward-skewed rotor and the backward-skewed rotor.In present study
aerodynamic and aeroacoustic performance of these three type rotors was measured and analyzed.The results show that the forward-skewed rotor may reduce noise effectively and extend the range of steady operation compared to the radial rotor.With the same skew angle
both the aerodynamic and aeroacoustic performance of forward-skewed rotor is better than that of the backward-skewed one.The performance difference comes from the direction of blade radial force.The tip flow condition of forward-skewed rotor is better
