Very good description of the cavitation effect Bunk! Much better than the ones I've read in the past. Most interesting. There are a lot of very cool subjects involving boats/ships etc.............By the way did you realize that when you crack your finger joints and make them ‘pop’ the noise is actually cavitation inside the joint. The ‘pop’ is the gas bubble collapsing within the joint as you cause a sudden reduction in pressure by opening the joint. The more often you do this the more damage you do to the joint and cavitation erosion will eventually cause arthritis.
The last paragraph re arthritis is particularly interesting to me as I have Rheumatoid arthritis myself. I thought the clicking you referred to that kids do, was just bones clicking. My joints are all very clicky but that's mostly due to large gaps and worn cartliage etc from the RA erosion. Some of it may also be cavitation as you said.
