Experiment Study on Lift and Resistance Wind Energy Fan

At present, wind energy is mainly used for the power generation and its technology has been relatively mature. This paper researches that wind energy is utilized to directly drive the axial fan with the vertical wind turbine, to realize the underground ventilation. This integrated equipment is called wind energy fan (WEF). In this way, the energy loss, which is caused by the repeated energy conversion due to the wind energy generation and the motor-driven fan, will be greatly decreased. According to the rational design and calculation of model schemes, the experiment platform is established to analyze the performance of lift and resistance wind energy fan. Meanwhile, the experiment tests the rotating speed of WEF and the air volume of experiment duct under transmission ratios of 1:1, 1:5.17 and 1:10. The experiment results show that the efficiency of lift WEF is higher than that of resistance WEF. The transmission ratio has a big influence on the air volume of wind energy fan, and the certain transmission ratio should be selected to improve ventilation efficiency. The investigation shows this scheme is an effective wind energy technology to realize the active utilization of wind energy in underground engineering ventilation.
