The Prandtl-Meyer angle () after a deflection at a wedge refers to the change in the Prandtl-Meyer angle due to the deflection of a supersonic flow around a wedge-shaped body or surface. The Prandtl-Meyer angle is a critical concept in supersonic aerodynamics that characterizes the angular deviation of the flow direction from a reference direction.
