10.17 Consider the point at (r, φ) = (r*, π/2) at a distance r* directly above the
corner. The streamline through this point, and the streamline along the surface,
Both μ and ν are functions of the local Mach number M at point P. Thus, the
From the isentropic relation for area ratio given by Equation (10.32), we have
Since sin μ = , this becomes
Repeating, the polar angle of point P is
By using M as a parameter in equations (1) and (2), various points on the
