The “Prandtl-Meyer angle after a deflection,” often denoted as , refers to the angular deviation of the flow direction after it has been deflected due to interactions with shock waves or other flow disturbances. This concept is widely used in the analysis of compressible fluid dynamics, especially in scenarios involving changes in flow direction.
