shed vortex meaning in English
脱出涡
Examples
- Based on an engineering background , through numerical simulation of the flow field in the hp turbine of the energy efficient engine ( e3 ) , the article research the unsteady flow in a transonic turbine stage , the unsteady phenomena in the stage include the shockwave , wake , shedding vortex , endwall vortex , passage vortex and leakage vortex , etc . there are two shockwaves generated on the vane the tailing edge , one on suction side is named moving shockwave , and name another on pressure side steady shockwave
本文首先对于研究的意义和国内外研究的现状做了简要的介绍，再从某工程背景出发，通过对e3发动机高压涡轮内流场的数值模拟，研究了干涉的周期性的问题，以及涡轮级内常见的非定常现象：激波、尾迹、脱落涡、根脚涡、通道涡、漏流涡。导向器尾缘会出现两道激波，在吸力面的激波可称为“运动”激波，压力面的激波可称为“定常”激波。 - The vortex simulated in this article include the shedding vortex induced by the vane trailing edge boundary layer , the endwall vortex generated by the endwall boundary layer interaction , the passage vortex generated by the rotor rotation , and the leakage vortex generated by the tip clearance flow
涡轮级内的涡运动包括：导向器叶片尾缘附而层引起的脱落涡；转子通道内转子的旋转运动产生的通道涡；根脚区两个端壁附面层干涉，形成的根脚涡；存在叶尖漏流时，出现的漏流涡。
