Question about Supercavitation

[JSLTIGER]

You know, something just occurred to me...

Is there a depth limitation for supercavitation? If not, then hypothetically, couldn't a sub dive to immense depths within the pocket that supercavitation creates? After all, the pressure would be significantly reduced within the pocket...that's the entire point of the technology, isn't it? To reduce the water's force of drag on an object. Why wouldn't that extend to pressure as well?

Yes maybe but what about noise also?

And there is limitations on how far you can go with hydrodynamics.

[JSLTIGER]

Well, it makes sense that there'd be a significant amount of noise involved, as the pocket is going to collapse on itself once the object passes through. Additionally, most forms of propulsion through this kind of pocket (at the moment, rockets seem to be pre-eminent) are not necessarily geared towards silence.

good question... i admit, i dunno...

strange things happen at high pressure and deeper depths... by strange, i mean, unexpected things...

maybe the pressure at great depths would amplify the cavitation effect...

hey... i really don't know...
