The flow impinges at an absolute flow angle of 70 … WebConsider an axial compressor blade row. The inlet velocity is 150 m/s and is in the axial direction. The blade speed is 180 m/s and the relative outlet angle is 30 degree to axial. Assuming constant axial velocity through the blade row calculate the relative angle at the inlet and the absolute swirl velocity and absolute flow angle at the outlet.
Webassumes that the relative flow angle at exit of the rotor is the supplementary of the relative flow angle at rotor inlet (4 = − β π β 1). However, it has not been recognized previously in the open literature that this theoretical model predicts that the flow angle at exit of the rotor, β. 4, changes quite a lot when the blade-jet velocity ...
