AI Thread Summary
Cavitation occurs when the pressure at any point around a sphere moving through an incompressible fluid drops below the fluid's vapor pressure. This phenomenon is influenced by various factors, including viscosity, density, and pressure differentials. Flow separation behind the sphere can create an adverse pressure gradient, contributing to the conditions necessary for cavitation. A simplified understanding suggests that sufficient flow separation is crucial for this process. Overall, the interaction of these variables determines the likelihood of cavitation occurring.

For a sphere moving through an incompressible fluid, what is the condition for cavitation to occur?
 
Physics news on Phys.org
Well--this is a bit more complex than it may seem--you are dealing with a lot of different variables ---like viscosity/density/delta pressure/------perhaps a google search under "Sphere+cavitation" would help. Try that--and I will look also.

Maybe there is some sort of simplified answer for it? The question is suppoesed to be a relatively short one...
 
Cavitation will happen when the pressure at any point drops below the fliud's vapor pressure. This can happen around a sphere if there is sufficient enough flow separation happens behind the sphere, creating an adverse pressure gradient.

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
