vortex-breakdown

基本解释

The action of the oscillation toward vortex-breakdown in due partly to the effect.
振动对涡破裂的作用部分地与这种效应有关。
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.
定常数值模拟结果表明，近失速工况下泄漏涡在叶片通道内部发生破碎，涡破碎使得堆积在机匣壁上的低能流体迅速扩散，对来流产生了很大的阻塞效应。
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，在破碎大尺度旋涡和减少泄漏损失方面，B型防涡圈明显优于A型防涡圈。
