Numerical Study of Plume-Induced Flow Separation
Abstract
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 lb/sec, 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.
