The performance of the centrifugal compressor at different diffuser stagger angles and different inlet guide vane(IGV) prewhirl angles are measured. 對不同擴(kuò)壓器進(jìn)口安裝角下離心壓縮機(jī)的性能進(jìn)行了實(shí)驗(yàn)研究，并詳細(xì)計算分析了相應(yīng)的流場分布。
The 3D, viscous flow field in centrifugal compressors stage with three vane heights of straight plate diffuser was numerically analyzed by using of CFD method. 通過對氣流流動參數(shù)在不同葉高擴(kuò)壓器內(nèi)的分布規(guī)律的分析，給出了擴(kuò)壓器葉片高度對氣流的影響特點(diǎn)，為流體機(jī)械部件的優(yōu)化提供了數(shù)值依據(jù)。
It is found that vane diffuser restrains the influence of the volute on the impeller. 發(fā)現(xiàn)了葉片擴(kuò)壓器對遏制蝸殼對葉輪內(nèi)流場的影響有明顯的作用。
