If you have to explain lift, you must start with Bernoulli.
Are you trying to tell us we need to apply Navier-Stokes to understand the basics about static and dynamic pressure around an airfoil, a boat rudder and all that? No, sorry, Bernoulli is more than sufficient. To calculate the effects over a rudder in real applications, for sure, that is exactly how...Jump to post

I didn't say that the vapour pressure changes. I said the the static pressure drops below the vapour pressure, and that causes cavitation.

It is primarily a function of the static pressure of the fluid dropping below the vapour pressure of the fluid. If and where that happens, you can (or will) have cavitation. And why does the static pressure drop in certain areas? Because the dynamic pressure (i.e. the local velocity) rises, while t...Jump to post
By 'phase change' do you mean liquid turning to gas? My understanding of cavitation is that it's when the pressure over a boat/ship's propeller surface drops to the point where gas forms (it effectively 'boils'). Prop blades nearer the surface are more prone to cavitation due to the lower pressure ...Jump to post

Can you say that movement causes lift? I am not comfortable with that word, it is more of two results of the same interaction for me.

Pressure differential explanation is perfectly correct. After all, pressure is the force of air interacting with the surface, and there has to be such force in order for the wing to generate lift. Now higher pressure air under the wing is trying to escape down, and air above the wing moves down as ...Jump to post

First, lift is caused by the differential pressure above and below the wing, the faster flow is on the upper surface, not the lower.
