Numerical Simulation of Axial Fan based on Different Circulation Index of Impeller
摘要
Abstract
Advanced CFD technology is used to comparative simulate designed fan by different circulation index of impeller methods (equal circulation,variable circulation and optimized circulation).The existing fan was measured to verify the correct-ness of the physical model.It was found that optimized method can be improved about three percent in efficiency compared to an-other two methods.Efficiency curve of optimized circulation index is relatively cliffy.Efficiency of optimized circulation index may under equal circulation method when actual operation condition deviates from design condition.关键词
