blade passage

基本解释

It usually appears at the RF, blade passage frequency and commutator brush frequency, and their higher harmonics.
它通常出現在射頻，葉片通過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.
介紹了汽輪機動葉片葉身平均對流換熱表麪傳熱系數和葉片流道下壁麪對流換熱表麪傳熱系數的計算方法和計算公式。
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.
低比轉速泵的高敭程決定了葉片流道內逆壓梯度比較高，這種壓力分佈使得水流易於在葉片表麪脫流分離，這一現象甚至在泵的設計點也難以避免。
