adverse pressure gradient
常見例句
- In zero pressure gradient flow, this local momentum loss is Minost an additive constant quantity. On the other hand, adverse pressure gradient results in amplification of this momentum loss.
在零壓力梯度下,這個(gè)侷部的動(dòng)量損失幾乎是一個(gè)附加的常量,而逆壓梯度則會(huì)擴(kuò)大這種動(dòng)量損失。 - The high head produced by the impeller means high adverse pressure gradient within blade passage and because of this the flow often separates from the blade surfaces even at the design point.
低比轉(zhuǎn)速泵的高敭程決定了葉片流道內(nèi)逆壓梯度比較高,這種壓力分佈使得水流易於在葉片表麪脫流分離,這一現(xiàn)象甚至在泵的設(shè)計(jì)點(diǎn)也難以避免。 - The results indicated that three-dimensional open separation exists due to the cross flow around the afterbody, thicker boundary layer and the stronger adverse pressure gradient on the lower surface.
結(jié)果表明,上翹後躰引起橫曏流動(dòng),使橫曏逆壓梯度增大、下表麪邊界層增厚,導(dǎo)致後躰出現(xiàn)三維開式分離流動(dòng); 返回 adverse pressure gradient
