An experimental investigation of effects of two kinds of streamwise-grooved blades on the performance of an axial-flow fan was performed on an axial fantest rig.
Calculating Method for rotary blade loss of axial fan is given. Calculations on the lossing and routine lossing models are carried out by the use of 20 groups of fantest data.
