There exists different designs of supersonic inlets for jet engines. A normal shock forms ahead of the inlet, with an attendant large loss in total pressure. While, in an oblique shock, a central cone creates an oblique shock wave and the flow subsequently passes through arelatively weak normal shock at the lip of the inlet.

The paradox is immediately removed when viscosity is included in the flow. The shear stress creates drag is self-evident from the figure and the pressure drag created by flow separation.

An experiment with the cylinder spinning about its axis at relatively high revolutions per minute results in a finite lift. Also, by this time you might be thinking of other situations: spin on a baseball causes it to curve, and spin on a golf ball causes it to hook or slice. Clearly, in real life there are non symmetric aerodynamic forces acting on these symmetric, spinning bodies. So the concept of lifting flow over a cylinder leads directly to the theory of the lift generated by airfoils.

The typical variation of lift coefficient with angle of attack for an airfoil. At low-to-moderate angles of attack, cl varies linearly with α; the slope of this straight line is denoted by a0 and is called the lift slope.

It can be noted that the turbulent boundary layer thickness is larger than the laminar boundary layer thickness.
The turbulent profile is “fatter,” or fuller, than the laminar profile. For the turbulent profile, from the outer edge to a point near the surface, the velocity remains reasonably close to the freestream velocity; it then rapidly decreases to zero at the surface. In contrast, the laminar velocity profile gradually decreases to zero from the outer edge to the surface.

The fundamental difference between inviscid and viscous flow lies in the consideration of viscosity, which is the fluid's internal resistance to flow (often thought of as "stickiness" or internal friction).
