Prandtl-Meyer function
Additional recommended knowledgePrandtl-Meyer function describes the angle through which a flow can turn isentropically for the given initial and final Mach number. It is the maximum angle through which a sonic (M = 1) flow can be turned around a convex corner. For an ideal gas, it is expressed as follows, where, is the Prandtl-Meyer function, M is the Mach number of the flow and γ is the ratio of the specific heat capacities. By convention, the constant of integration is selected such that As Mach number varies from 1 to , takes values from 0 to , where
where, θ is the absolute value of the angle through which the flow turns, M is the flow Mach number and the suffixes "1" and "2" denote the initial and final conditions respectively. See alsoReferences
