Book Description
Abstract: The characteristic differential equations are set up for two-dimensional potential flows. The second form of the characteristic differential equations, involving only the magnitude of the velocity and the deflection angle, are integrated. The methods of O. Walchner and of Prandtl and Busemann are discussed. Busemann's development of the pressure variation for small deflection angles is given and applied to the example of a circular arc profile. Tables are provided giving the relation between deflection angle, pressure, velocity, Mach number and Mach angle for isentropic changes of state for air (k [kappa] = 1.405).
