旋涡形成 meaning in Chinese

eddy generation

Eventually mode a and b coexist in the wake , which confirms the previous studies . besides , the present paper finds that downstream the streamwise
从圆柱表面到旋涡形成区、到近尾迹再到下游尾迹流向涡结构从模式a转换到模式b 、双涡对模式、再恢复为模式a 。
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。
