The Prandtl-Meyer function (ν) for internal grid point three represents a mathematical function that relates the Mach number (M) of the flow at that specific grid point to the associated turning angle (ν) in radians. The Prandtl-Meyer function ν is important in the analysis of compressible flow, particularly in supersonic and hypersonic flows. It helps determine the turning angle of the flow as it passes through changes in Mach number, such as expansion or compression waves, at internal grid point three or any other location within the flow field.
