Supercavitation - Wikipedia
网页Supercavitation is the use of a cavitation bubble to reduce skin friction drag on a submerged object and enable high speeds. Applications include torpedoes and propellers, but in theory, the technique could be extended to an entire underwater vessel.
超空化 - 百度百科
网页超空化（super cavitation）亦称超空穴，是一种极端形态的 空化 现象。 当超空化现象发生时，整个绕流体的近壁区域内是汽液两相的混合流。 当压力足够低时，将形成充满汽相的“ 空穴 ”，称 超空泡。 在物体与液体之间的相对运动速度没有达到足够低压的条件下，也可人工注入气体，形成覆盖物体大部分表面或全部表面的内部主要含气体的“通气超空泡”。 中文名. 超空化. 外文名. super cavitation. 概 念. 一种极端形态的空化现象. 相 关. 超空泡. 一级学科. …
