有间隙涡轮叶栅壁面流谱实验与数值模拟研究 - Using the topological rules of the surface flow pattern , the separation configurations on the suction surface at different bowed angles is discussed
应用壁面流谱的拓扑法则，详细讨论了不同弯角下的分离形态。 - 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 - Although the knowledge of wind effects on tall buildings has significantly improved over the last decades , an understanding of the mechanism that the atmospheric flow field to various wind include effects on structures has not been developed sufficiently for formulation of functional expressions . not only is the wind approaching a building complex , but the flow pattern generated around a building is complicated by the distortion of the mean flow field , the flow separation , the vortex formation , and the wake development
在过去的几十年里,虽然人们对高层建筑风效应的了解已有显著提高,但对大气流场与结构物各种风致响应的关系还不能用解析表达式加以描述。由于平均流场的奇变、流动分离、旋涡形成以及紊流的发展,不仅使得流向建筑物的风,而且使得绕建筑物的流谱变得十分复杂。
