Supercavitation: Science Fiction or High Speed Reality?
China’s Harbin Institute of Technology’s Complex Flow and Heat Transfer Laboratory has made a breakthrough in supercavitation technology that could lead to significant advances in everything from maritime shipping to naval warfare. It has also led to utterly insane claims that go completely overboard.
Before we get to supercavitation, let’s discuss plain old cavitation, which is a fluid dynamics phenomenon that occurs when something moves through a liquid so fast that it ends up creating an area of pressure low enough that the liquid actually boils and turns into a small pocket of vapor — in other words, a bubble. A couple things occur as a result: One, the bubble collapses violently, creating a shockwave and a powerful microjet of water. Two, bubbles on the surface of the fast-moving object serve to reduce drag.
