Laminar Mach 26 flow past a blunt-nosed cone with a spherical after- body that injects mass axially from its base into the air, was studied in two finite difference calculations. The mass injection rate for both calculations was 0.15 lbsec, and Reynolds numbers relative to base diameter were 735 and 4150. Computations were performed with a code AFTON 2A which, apart from discretization error, generates solutions to the time-dependent Navier-Stokes equations for axisymmetric systems that contain mass-injecting bodies. In both cases steady flow was approached asymptotically in time from initial flow fields derived from simple inviscid theory.
