Evaluation of Fan Blade Load Distributions with Momentum Source
抄録
The load distribution of the fan blade is basic concept to design fan s. The momentum source model is proposed to design the blade geometry. It is checked the performance of the sirocco fan for the various momentum source distributions in previous paper. In this paper, the momentum source distributions for the loaded blade are estimated. The components of momentum sources are checked. It is pointe d out that the momentum sources are mainly derived from the deviation of the flow characteristics . It is cleared for the sirocco fan blade that the spanwise momentum source is almost ze ro and the radial momentum source is very small, but the tangential momentum source is very large. The tangential source is mainly caused by the pressure difference between pressure and suction side of blade. Especially the pressure difference near the leading edge is very large because of the leading edge separation.
