| Abstract: | The influence of the axial gap between blades and rear guide blades on performance of mine-used small axial flow fans is analyzed using CFD technology after numerically calculating the axial flow fan.The results show that the flow rate and the total pressure of the fan increase with the decrease in the axial gap,thus the efficiency of the total pressure improves and the performance of the axial flow fan enhances. |
