on the bottom...................I would say no Frank. it could if designed properly, but most aircraft are fairly flat along the bottom. as long as the fuselage is expanding, the boundary layer remains thin and attached, due to the increase in pressure. think of it like an airfoil..............the air flows over the top surface and the pressure builds. boundary layer is laminar and thin, but as we get to the peak of the curve, the pressure reduces slightly and the boundary layer starts to thicken and detach, especially as AOA rises. kinda the same thing with a fuse too. pressure builds as the body expands and then tapers towards the rear. for a NACA inlet to work properly, we've got to place it at a point where this pressure is at it's best potential to recover in the duct.
