Wing vs wall to wall wing,total drag comparation at same AoA?
I agree with your conclusion that the wall-to-wall wing has more drag than a free-flying wing at the same angle of attack.
But what is the point of this comparison?
People build wings to create lift. These wings might be on airplanes, but also on helicopters, propellers, the fin keels of boats or the blades in turbo machinery. Their purpose is in all cases to create lift. Not drag. Drag is an accepted price for that lift creation, but not their purpose.
So it is pointless to ask for a drag comparison when disregarding lift at the same time. This is akin to asking if a wing that is not moving creates no drag.
You don't even let us know the wingspan of those hypothetical wings. Are they in the same windtunnel, so the free-flight one has less aspect ratio, span and surface? Or is it the same wing, with the windtunnel removed?
So please stop repeating the same pointless and insufficiently specified question over and over. You will not get useable insights because the answers can not be helpful.
