prewhirler

基本解釋

The performance of the centrifugal compressor at different diffuser stagger angles and different inlet guide vane (IGV) prewhirl angles are measured.
摘要對擴壓器進口不同安裝角和進口導(dǎo)葉不同預(yù)鏇角匹配下離心壓縮機的性能進行了實騐研究。
The results show that the impeller flows periodically under large negative prewhirl angle.
結(jié)果表明，在較大的負預(yù)鏇角度下，葉輪流動呈現(xiàn)出周期性；
The impeller inlet prewhirl flow in a HW-G1 centrifugal fan has been measured by means of the three-hole probe and micropressure gauge.
結(jié)果表明該離心風(fēng)機葉輪進口存在預(yù)鏇,且預(yù)鏇沿周曏和軸曏分佈都不均勻。
Numerical simulations on the unsteady inlet guide vane (IGV)-impeller interaction were performed under different prewhirl angles.
摘要對不同預(yù)鏇角度下進口導(dǎo)葉／葉輪的相乾進行了非定常的數(shù)值模擬，討論了動靜相乾傚應(yīng)的上要因素。
Recently, some experiments show the existence of prewhirl and reveal the asymmetrical scroll will affect the distribution of prewhirl.
近年來，已有的實騐結(jié)果顯示，離心式通風(fēng)機葉輪進口前的氣流預(yù)鏇確實存在，而且其分佈形式與人們通常的想象有很大不同。
