Design of a High Efficiency Axial Flow Fan By Applying Optimization Algorithm
Abstract
The present paper deals with the optimization study of an axial flow fan, which optimizes 3D fan rotor blade
geometry by the application of optimization algorithm to the design variables of spanwisecamber, stagger angles and chord
lengths for improving fan performance and maximizing fan efficiency. Through the design optimization process of fan rotor
blade, optimal fan rotor is obtained and then coupled with outlet guide vane. Computational fluid dynamics analysis is
conducted to verify the performance and efficiency of the present optimal fan design. The design values of performance and
efficiency of the present optimal fan agree well with the CFD results and the present optimal fan design gives the efficiency
improvement of 6.7% compared to the initial design.
