Hydroxy from Cavitation

[Dave45]

Ok I posted the info in the cavitation thread but know responses maybe a dumb idea ?
What is the gas produced in mechanical cavitation,propeller,hydrofoil.
I believe its hydroxy and I believe it can be collected

by "mechanical cavitation" are you refering to the compression pumps, where there is a rotor with holes in it, spinning in a tight chamber

that "gas" is air that is trapped in the water. as the vibrational energy exerts changing pressure onto the water,
the air compresses, however the water cannot, thus it creates "bubbles" during the decompresion phase of hte oscillation. The compression causes the water to heat, this expands the bubbles;

its kind of like the way the air bubbles collect to the bottom of a pot thats about to boil.

the gas that forms on the tips of a propeller or a hydrofoil, ship builders design propellers to reduce cavitation but I believe we can build a hydrofoil that will increase cavitation add more hydrofoils means more gas, is this gas hydrogen and oxygen ?

G'day all,

Cavitation bubbles are not a gas or steam. They are small spaces of VACUUM that are caused when one part of the water is moving so fast that the water behind it cannot follow in time. This small vacuum eventually collapses creating a strong pulse that is destructive to equipment.

as a hydrofoil moves through water it will form cavitation bubbles
