摘要

基于风扇参数化设计和数值模拟程序

分析风扇各主要结构参数对其气动性能的影响

为进一步的优化设计提供了条件.采用并行计算流体力学(CFD)方法

基于组合优化策略(正交实验设计、响应面模型、遗传算法和混合整型算法)以多工作点流量系数平均值最大为目标函数对风扇进行多参数结构优化.8025型轴流风扇的优化结果比初步设计方案的性能提高14.5%.

Abstract

Based on the procedure of the parametric design and numerical simulation of the fan

investigations were made in detail on the effect of various design parameters on the aerodynamic performance of the fan

which can provide deep understanding for the optimization of the fan.The multi-parameter constrained optimization procedures based on the combination algorithms of design of experiments(DOE)

response surface models(RSM)

genetic algorithm(GA) and mixed integer optimization(MOST)

were carried out on 8025 fan for maximizing the coefficient of flow rate over the operating range rather than at a single operating condition with parallel computational fluid dynamics(CFD).Results show that aerodynamic average performance of the optimal fan is increased by 14.5 % when compared to the initial fan.
