生存还是毁灭... - 渗透到流动浴中的液体射流的不稳定性，
To be, or not to be... -instabilities on a liquid jet penetrated into a flowing bath-
摘要：
我们进行了一系列的实验，特别感兴趣的渗透过程和不稳定性上出现的液体射流冲击到液体的同类流动在一个通道。冲击射流进入流动熔池时伴随着周围不混溶气体的卷吸，导致冲击射流被卷吸气体包裹成“鞘层”。这种鞘层的形成使撞击的射流能够在通道中的流体中存活而不聚结，直到被包围的空气鞘层破裂。有时候，在穿透射流的尖端会形成一个夹带空气的“帽”，射流会像一个长气球一样伸长。
英文摘要：
We conduct a series of experiments with a special interest on a penetration process and instabilities arisen on a liquid jet impinged to a liquid of the same kind flowing in a channel. The impinged jet penetrates into the flowing bath accompanying with entrainment of the ambient immiscible gas, which results in the impinged jet wrapped by the entrained gas as a 'sheath.' This sheath formation enables the impinged jet to survive in the fluid in the channel without coalescing until the entrained-air sheath breaks down. Occasionally a 'cap' of the entrained air is formed at the tip of the penetrated jet, and the jet elongates like a long balloon.
