Two kinds of distinctive wake vortices were identified from the experimental results, namely the jet wake vortices and the crossflow wake vortices.
由实验结果可得到两种明显的尾迹涡结构、即射流尾迹涡和横流尾迹涡。
The wake vortices of an impinging jet in crossflow were studied experimentally by means of laser-induced fluorescence (LIF) flow visualization and particle image velocimetry (PIV) measurement.
本文采用LIF(激光诱导荧光)流动显示和PIV(粒子图像速度场仪)测量对横流冲击射流的尾迹涡结构进行了实验研究。
When fish swim, they leave little swirling vortices in their wake. By swimming together in a school, they can transfer energy to one another through these vortices.
当鱼儿游动时，鱼尾会留下一个个小漩涡，当它们成群游动时，它们可以通过这些漩涡转换能量。
