The Prandtl-Meyer flow angle (θ) at internal grid point three represents the angle at which the flow direction deviates from the local direction of the streamlines at that specific point within a computational grid. This flow angle is measured in radians. The Prandtl-Meyer flow angle is a critical parameter in the analysis of compressible flows, particularly in the study of supersonic and hypersonic flows. It is often used in conjunction with the Prandtl-Meyer function (ν(M)), which relates the Mach number (M) to the turning angle (ν) in radians, to determine how the flow behaves as it encounters changes in Mach number and other flow properties.
