Abstract

Numerical calculations of the flow in a plane supersonic boundary layer of vibrationally excited gas in locally self-similar and original formulations were carried out. Some characteristic conditions of the external flow and heat transfer at the boundary were considered. It is shown that in all the cases of locally self-similar solutions the profiles of hydrodynamic variables converge to some limit values for the longitudinal coordinate x = 8 - 15. For all regimes, the maximum local deviation of these limits from profiles calculated in the full formulation does not exceed 5 %. This justifies the use of easily calculated locally self-similar solutions in corresponded problems of the linear stability theory.
