叶顶 meaning in English

blade tip
tip

It was found that the introduce of tip clearance deteriorate the overall performance of the compressor rotor
数值结果表明叶顶间隙的引入恶化了压气机转子的性能。
At the same time , tip leakage induced by pressure gradient and relative motion between the blade tip and the shroud wall is found to have a major influence on detailed flow properties in tip region of rotor passage
同时，由于转子叶片压力面和吸力面之间压力梯度以及叶顶与机匣之问的相对运动产生的间隙流对转子通道内的细微流动结构有较大的影响。
Abstract : this paper uses the topology theory to analyze the surface flow spectrums of straight , positively curved and negatively curved cascades with relative tip clearances of 0 . 023 and 0 . 036 , finds apparent differences of topology and vortex structures in the blade tip and the suction side wall corner of single type of cascade with this two clearances , and studies the mechanism of the difference formation as well as their effects on the energy loss
文摘:应用拓扑原理分析了叶顶相对间隙为0 . 023和0 . 036的涡轮直叶栅和正、反弯叶栅的壁面流谱,发现在两种间隙下同类叶栅的拓扑与旋涡结构在叶顶和吸力面壁角明显不同,探讨了差别形成的机理及其对能量损失的影响
