역설계 방법을 사용한 축류홴 설계

The axial fans for cooling condenser were designed by inverse design code TURBOdesign-1. The parameters of the inverse design were set by DOE(design of experiments). By changing the design parameters, such as the distribution of the blade loading, the spanwise circulation distribution and the stacking, 32 different fan designs were created. The overall performances and the local flow fields of these fans were computed by using a commercial CFD code. The results of the CFDcomputations were analyzed by DOE. The pressure rise and the efficiency were selected as the main responses and the main effects of the design parameters onthe responses were discussed. These procedures give a good way for the screening the parameters and the optimum design.
