Tramps like us, Baby we were born to run...
I love the way AJ talks. Layman's is a language I can understand.

Layman's works for me too...I'll leave Roman to Caesar and Whatever he's saying to Trump.My Boss talks to me in a different language when I put the hammer down!!!!!!!!!!!!!!I love the way AJ talks. Layman's is a language I can understand.
Great idea! Let's fix everything wrong about aero on the interwebs! I would start here...
I thought the direction that circulation bubbles rotate was obvious. I was wrong.
Understand the difference between Adverse Pressure Gradient and Flow Separation. Don't use one to sound smarter than the rest of YouTube.
And I'm not sure where to start with this one:
Somehow, I don't think he's talking about your posts.
Kyle is the guy we worked with on our new wings, diffusors, canards, end plates, splitters and tunnels, and some other stuff right before he went to F1.
Oh I'm sure he does. Everyone does. But he has a better grasp on aero then 99.99% of people. So I'll trust him and feel I am extremely fortunate to have worked with him.He doesn't make mistakes? Lots of funny ones in his videos.

Please explain your opinion. I believe you were the one a page or two ago that said splitter angle doesn't matter? I have CFD sims, as well as actual in the wind tunnel experience debunking that.So he was the one that did some of this work for you?

There's a lot that's wrong with this comparison.

Just saying.

False. Despite the fact that the pressure raises in the trailing part of the tunnel, the net Df gain is to the tune of almost double that of a flat splitter. CFD numbers support that. The ride height and rake of the main splitter body was the same in that side by side shot. Its mainly to show how much of a gain tunnels can have.View attachment 8783
And the more I look at this, the worse it seems. Looks like the tunnel itself would net a lift reaction.
Again, I would much rather have a splitter that has some forward rake to it and be 3" off the ground, then one with negative rake and be 2" off the ground. You do you tho.Oh, it does matter when you make a comparison using different ride heights, splitter shapes, splitter profiles and don't make a proper comparison changing only the single element in question.

In the context of flyhalf's add-on lip, I stand by that statement. Most, if any change comes from vertical movement of the leading edge.

Not even sure what you mean there.Again, I would much rather have a splitter that has some forward rake to it and be 3" off the ground, then one with negative rake and be 2" off the ground. You do you tho.
Yes, as mentioned above, its to show the differences that adding tunnels can make to flat splitters. The tunneled setup made about double the downforce as the flat splitter
Again, I disagree with this one. But you can do stuff your way if you want. Doesn't bother me at all.

If we look at these side channels, look at where they're venting. This one here vents almost immediately into the tire. Now, if you're sort-of diffusing your air up, and then it's hitting this high pressure area on the front of your tire that's very turbulent, are you really getting an advantage here? (dramatic pause and hand gesturing) ...not really.

But, if you can, try and avoid venting a diffuser into a tire, or anything like that. It's really not gonna do that much for you.
Ride height in CFD is based off chassis height since we were doing full chassis runs and could add rake to the entire chassis. So the tunneled splitter had a radiused edge to feed more air under the splitter, hence the splitter being a little lower with a small rake at the rear, but ride height the same. Hope that makes sense. And rake is the tilt or angle of either the splitter or chassis. Not quite sure how you feel this is deceptive as we are literally showing the pressure plots of CFD work we've done.Look at the red lines I inserted in the comparison drawing above. The lines on both are copy pasted, so they're the same angle and length. There are clearly differences between the two in both rake and ride height that have nothing to do with the tunnels and greatly skew the way this appears to the lay person.
Not even sure what you mean there.
Then it either fails to show what you intend or is outright deceptive. And that does bother me.
Even his own analysis says not to put a diffuser in front of a tire:Kyle said:13:57 to 14:17
