Numerical simulation of gas flow past scale model of hypersonic vehicle in wind tunnel

Flow of gas mixture around and inside a scale model of hypersonic vehicle is simulated with use of the FlowVision software. The model is placed in a wind tunnel. All the solid surfaces present in the experiments are taken into account in the calculations. Calculations are compared with experimental data obtained in two runs: without burning hydrogen in the combustion chamber (cold run) and with burning hydrogen (hot run). The computational grids are built automatically with use of different adaptation options available in FlowVision. The agreement of numerical results with experimental data is good.
