Physics of Cavitation: Cavitation inception

Cavitation inception is important for two reasons. The first reason is that the radiated noise level of any form of cavitation is an order of magnitude higher than the noise level of a non-cavitating flow. This is used by Navy ships to detect and locate other ships and by torpedo’s to home in on the ship. This is the Navy problem of cavitation inception and the inception speed of a navy ship is very important.
