blade passage

基本解釋

It usually appears at the RF, blade passage frequency and commutator brush frequency, and their higher harmonics.
它通常出現(xiàn)在射頻，葉片通過(guò)頻率和整流子刷頻率，其高次諧波。
Method and formulae for calculating the mean forced convection heat-transfer coefficient of the blade surface, as well as for the blade passage's bottom wall, are introduced.
介紹了汽輪機(jī)動(dòng)葉片葉身平均對(duì)流換熱表面?zhèn)鳠嵯禂?shù)和葉片流道下壁面對(duì)流換熱表面?zhèn)鳠嵯禂?shù)的計(jì)算方法和計(jì)算公式。
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)速泵的高揚(yáng)程決定了葉片流道內(nèi)逆壓梯度比較高，這種壓力分布使得水流易于在葉片表面脫流分離，這一現(xiàn)象甚至在泵的設(shè)計(jì)點(diǎn)也難以避免。
