Is there a speed or condition that is calculable for Supercavitation to work as in a Land Speed Record...or even in atmosphere..?  Does it only work with fluids?...

I understand it would not work for aircraft as it would take away the flow to control surfaces.

Thanks in advance  

I don't know anything but the people that do.

i think the point with cavitation is that bubbles are created from gases dissolved in the liquid where the local pressure is low enough (when the local flow is fast enough).  i think it is relevant to hypersonic planes, when the different gases in the atmosphere behave differently.

maybe you should start at the beginning (i'm designing a land speed record vehicle ...) and end with a question ...

Yes, it only works in liquids, cavitation is created when the local absolute pressure on the fluid drops below its vapor pressure.

Well, wait, I take that back.  It COULD work in solids too...but only for solids like graphite, that vaporize before they melt...so it wouldn't work to give you a LAND speed record, more of a tunneling speed record...
