Similarity between the heat transfer to a model in an underexpanded dissociated-air jet of a high-frequency plasmatron and to a sphere in a high-velocity flow in the terrestrial atmosphere

详细

On the basis of the local heat transfer modeling concept the parameters of supersonic flow past a cylindrical flat-faced model, 0.01m in radius, in an underexpanded dissociate-air jet of the VGU-4 high-frequency plasmatron are recalculated to the conditions of sphere entry in the terrestrial atmosphere. The heat transfer parameters, similar in the experiment and the atmospheric entry, are determined.
