    摘要:

    基于三維反問題設(shè)計(jì)方法和CFD技術(shù)，結(jié)合試驗(yàn)設(shè)計(jì)方法、響應(yīng)面方法和模擬退火優(yōu)化算法，建立了離心風(fēng)機(jī)葉片三維形狀的優(yōu)化設(shè)計(jì)方法。以葉輪效率為優(yōu)化目標(biāo)，以環(huán)量分布參數(shù)為優(yōu)化設(shè)計(jì)變量，進(jìn)行了離心風(fēng)機(jī)葉片的優(yōu)化設(shè)計(jì)，優(yōu)化設(shè)計(jì)結(jié)果葉輪效率提高了2.2%。根據(jù)建立的優(yōu)化設(shè)計(jì)變量和葉輪效率之間的響應(yīng)面函數(shù)關(guān)系式，分析了不同環(huán)量分布參數(shù)及參數(shù)間交互效應(yīng)對(duì)葉輪效率的影響，結(jié)果顯示輪轂進(jìn)口段環(huán)量分布對(duì)葉輪效率有較大影響；輪緣處的環(huán)量分布形式對(duì)葉輪效率影響更為顯著。

    Abstract:

    An optimization design method based on 3-D inverse design method and CFD was developed by combining design of experiment method, response surface method and simulated annealing optimization calculation. The method was applied to a centrifugal fan blade design by setting the impeller efficiency and the circulation distribution parameters as the optimization object and the optimization design variables respectively. The efficiency was improved by 2.2% with the optimization method. The effects of the circulation parameters and their interaction effects on the impeller efficiency were analyzed according to the constructed response surface between the design parameters and the impeller efficiency. It is shown that the inlet circulation distribution on the hub plays an important role on the efficiency. Comparing with the hub, the circulation distribution shape on the shroud has more influences on the efficiency.
