Confused about Cavitation?

Cavitation is an interesting topic when talking about high speed propulsion systems. It is also a topic that can be rather confusing. Indeed, whereas most vessels try to minimize cavitation, vessels using surface drive use cavitation in becoming more efficient.

The University of Texas Engineering Department is well-regarded in their expertise and research into cavitation (As well as their fluid dynamics program), and they have a web page that delves into a very easy to understand explanation of the topic, complete with some very instructive photos and diagrams.
