Numerical analysis of vortex structures and heat transfer in a supersonic flow past the junction of a blunt-fin body and a plate

We report on the results of numerical simulation of a supersonic laminar flow past the junction of a blunt-fin body and a plate. We analyze the gasdynamic and vortex structures of the flow, which are determined by the viscous–inviscid interaction. We consider the results indicating the qualitative and quantitative influence of key parameters such as the Mach number, the Reynolds number, the temperature factor, and the plate length on the flow structure and heat transfer.
