船舶反弯扭螺旋桨水力特性的数值模拟与分析 - A negative bowed blade increases the flow separation and the flow performance is reduced remarkably
反弯则使得叶栅内分离趋势增加，气动性能明显降低。 - The expressions of distributed bars of several normal cases in the practical engineering are presented based on the equalization of the slope of prestressed bars at the end of each curve at inflection point
以预应力筋在反弯点处每段曲线端点的斜率相等为基础，提出了实际工程中常用的几种情况的布筋表达式。 - However , for small span - to - depth ratio coupling beams are counter flexural deep beams restrained at their two ends and points of contraflexure at the center of the span , the rules of their carrying forces and deformation are not like common deep beams
但是，小跨高比连梁属于两端被约束，反弯点在跨中的反对称弯曲深梁，其受力和变形规律不同于一般深梁。 - 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
