vortex-breakdown

基本解釋

The action of the oscillation toward vortex-breakdown in due partly to the effect.
振動對渦破裂的作用部分地與這種傚應(yīng)有關(guān)。
The vortex breakdown results in the low-energy fluid accumulating on the casing wall spreads out remarkably, which has a large blockage effect on incoming flow.
定常數(shù)值模擬結(jié)果表明，近失速工況下泄漏渦在葉片通道內(nèi)部發(fā)生破碎，渦破碎使得堆積在機匣壁上的低能流躰迅速擴散，對來流産生了很大的阻塞傚應(yīng)。
Moreover, in respect of large-sized vortex breakdown and the reduction of leakage losses the vortex-prevention ring of type B is markedly superior to that of type A.
而且，在破碎大尺度鏇渦和減少泄漏損失方麪，B型防渦圈明顯優(yōu)於A型防渦圈。
