Abstract:

The results presented in this report are a continuation of the work reported earlier in ARL 63-117. This report describes methods and an IBM FORTRAN II program for the calculation of internal viscous and inviscid flow fields within the channels of a supersonic cascade. Methods included are 1 a second order Belotserkovskii procedure for calculating the flow field around the forward part of blunt blades, 2 a general method of characteristics procedure for calculating supersonic flow fields, 3 automatic procedures for calculating interactions of shocks of the same and opposite families, shock interactions with a wall and with a vortex sheet or slipstream, envelope shock formation, and 4 a finite-difference procedure for calculating the laminar boundary layer, which includes a method of suction calculation for maintaining a non-separated boundary layer under an adverse pressure gradient.
