Viscous-inviscid interaction and heat transfer in supersonic 3D laminar flow past a fin-body junction is investigated by means of numerical simulation. A laminar flow regimes at the freestream Mach number equal to 4, 5 and 6 are considered. Specifics of vortex structures and shock wave pattern in the interaction region are discussed. The Mach number effect on the predicted size of separation zone upstream of the fin and the plate Stanton number distribution are analysed. For the Mach number of 5, the temperature factor influence on heat transfer is investigated.
Results of numerical simulation of supersonic gas flow past a blunt fin mounted on a flat plate with developing laminar boundary layer are presented. The calculations cover flow cases with the freestream Mach number of 6.7 and three different Reynolds numbers. A detailed analysis of flow characteristics such as temperature and surface heat flux are presented. In the smaller Reynolds number case, solution is steady-state and agrees very well with known numerical and experimental data. In case of larger Re values, the flow becomes periodic. These regimes are characterized by self-excited non-linear oscillations with almost the same fundamental frequency.
