wing boundary layer aerodynamics - Pilotfriend

At the top of the boundary layer, the molecules move at the same speed as the molecules outside the boundary layer. This speed is called the free-stream velocity. The actual speed at which the molecules move depends upon the shape of the wing, the viscosity, or stickiness, of the air, and its compressibility (how much it can be compacted).

Aerodynamics and Theory of Flight, Forces of Flight, Lift ...

Because of the speed of the airframe and wings, etc., the air cannot move out of the way; instead of flowing around the wing, for example, the air cannot get out of the way fast enough, resulting in a compression of the air particles. Compressibility introduces radical changes in aerodynamic principles of high-speed flight.
