(Report No.5 A test on the effect of injection and suction to the boundary layer of the diffuser) ——A WindTunnel Test on the Entirety Model of Concentrated Wind Energy Turbine

The concentrated wind energy turbine is a new type of wind energy electric generator set which utilizes the rare wind energy after having concentrated it.Based on the data obtained by a great number of tests in wind tunnel,it is verified analytically that the wind concentrating effect could be enhanced and consequently the power output increased significantly when conducting injection and suction to the boundary layer of the diffuser inside the concentration device through high pressure injection nozztes and suction hotes by taking advantage of the high pressure formed around the outer side of the front inlet opening of wind concentrating device and of the low pressure existing at the side of the wind concentrating device instead of any other power source.
