Abstract

The present paper deals with the optimization study of a variable-pitch axial flow fan by combining fan design method of the FANDAS (FAN Design and Analysis System) code and optimization algorithm of the PIAnO (Process Integration, Automation and Optimization) code. The FANDAS code is used as fan design program to design 3D fan rotor blade geometry and to predict designed fan’s performance and efficiency, and it is also used as simulation engine for fan design optimization problem. The PIAnO code is used as optimization program to apply a function-based optimization algorithm to the FANDAS code and to find the optimal fan design solution for efficiency maximization. In this optimization study, spanwise camber, stagger angles and chord lengths of axial flow fan are selected as design variables and the design constraints are set to design flow capacity, total pressure, power and blade angles, solidities. Through the design optimization by combining the FANDAS and the PIAnO codes, optimal fan rotor blades are obtained and then they are coupled with existing outlet guide vanes to construct the final fan stage. Computational fluid dynamics (CFD) analyses are conducted to verify the performance and efficiency of the optimal fan design, and the CFD calculation results are matched well with the FANDAS predictions for performance and efficiency of optimal fan. The CFD results also show that the optimal fan design gives the efficiency improvement of about 6.7% compared to the initial design. Furthermore, the FANDAS performance predictions of the optimal fan under variable-pitch conditions show that the optimal fan can be operated with wide flow capacity range between 2000 and 5000 m 3/min and high efficiency above 80 % by adjusting fan rotor blade pitch angle.
