Abstract

Numerical simulations of the flow field around the interference zone near a blunt-fin/flat-plate junction in a laminar, hypersonic M = 6.7 flow have been carried out. It is known that such a protuberance produces a complex flow pattern, which includes shock/shock and shock/boundary layer interactions. Simulations were performed using a high resolution, Riemann based 3-dimensional Navier-Stokes solver. The operator split finite volume scheme incorporates a Godunov type inviscid solver while solving for the complete viscous terms. The preliminary results presented here are compared with experimental data concerning surface streamlines and heat flux distributions obtained under similar conditions. The variations in these are shown to be caused by localised regions of separation and reattachment due to vortical motion of the fluid in the interference zone.
