Hey fellas, lets discuss optimum NACA scoop shaping and sizing for cabin air.

I have found many templates, but they range in aspect ratio, depth, etc, quite drastically.

What I am getting at is, what shape (contouring of the sides), and size (width, length, and ramp angle) could or would be optimum? Furthermore, is there a series of formulas that will help determine optimum for a predetermined airspeed, and desired air volume and velocity?

Last but not least, is it worth designing and installing a duct that has a "closing" ramp to essentially close the duct from both the inside (inside through a eyeball vents and outside via the closed ramp). In my mind, it should be at the least save a bit due to form drag. Granted you still lose all laminar flow past the "closed" duct.
