相对间隙 meaning in English

relative gap

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
