Straight up aerodynamics

[Greg Locock]

I meant in the real world, not colourful fluid dynamics.

Before this becomes more of a back and forth flame war will you all please read this:

*note* this article will also help explain much of the basics that were asked for in the first page

Both approaches are right in all situations. Which approach should be employed is merely a matter of which is more convenient to use given the type of data available to characterize a particular flow pattern. The inability of one model or the other to explain lift production is really a problem of using a version of these laws that is oversimplified.

Amen.

I don't need to read the article. Action at a distance for pressures is a nonsense. The gas molecule hits another molecule and via a fairly straightforward piece of maths the state of both molecules is changed.

I'm sorry you are to stubborn to read a few pages written. Maybe if you actually had then you would see that you aren't actually contradicting the article but you are simply only looking at it from one side of the fence. I'm sorry you were raised as somebody who knows everything.

Message to the mods I know that this may sound odd but would it be possible for you to remove posts like the above for the simple reason of people just saying things baselessly and not even giving a snippet of information as to why....all to stop a nonsense flame war.

Big clue: I read the article. I was responding to somebody wittering on about particles.

I have no problem with Bernoulli as a descriptive summation of what is going on for millions and billions of molecules, but all the forces are generated by collisions between molecules

I refer to the old saying 'All models are wrong, some are useful'.

Should we start into the topic of circulation? Its somewhat esoteric seeing as how we can't see the circulation, but we an certainly see its influence on airspeed above and below a wing.

[Ciro Pabón]

... we can't see the circulation...

Please, speak for yourself.

Actual quote: "That damned Swede can actually see air."


JIC, that's Kelly Johnson.

He created Area 51, which may explain why he could see what you cannot...

... (and the Lockheed Electra, the P-38, the P-80, the SR-71, the U-2, the A-3, the T-33, the C-130, the F-117 and Skunk Works).

So, of course you can see circulation.

Wind tunnels are not there to see it, they are built to confirm what you see.
