Viscous Flowfield Calculations on Pointed Bodies at Angle of Attack in Nonuniform Freestreams

Abstract

determined from Eq. (1) and the condition of constant static pressure and total enthalpy. The inviscid flowfield is then calculated from a modified form of Rakich's three-dimensional method of characteristics (NASA TN D-5341). Typical results for the non-dimensional pressure (pb — Pb/p^v^) and inviscid surface Mach Number (Mb) are shown in Fig. 2 for a 20° half-angle cone at a = 10° and Mx = 3. For a velocity defect of A = 0.2 the surface Mach number goes to unity at x = 0.95 (based on B = 10) in the windward plane, and the three-dimensional method of characteristics cannot be continued beyond this point.
