Reply to "Functional air intake on c pillar?"

I had always thought it would be fun to change and test the boundary layer to trip it into the duct.

When an airplane reaches a high angle of attack (relative to the air flow) airplanes use Vortex Generators to spin the air. The spinning air comes back in contact with the wing and stays in the low pressure instead of separating.






A round object creates far more drag then an airfoil shape and creates a natural turbulent area behind it. Round objects are avoided in aircraft due to the drag created at high speeds:






HOWEVER...I would love to put a row of 3" long tubing the diameter of a pencil up the aft section of the door jam and see if that would not trip the air to bring a positive pressure in a smaller duct.
