CALCULATION OF A LAMINAR BOUNDARY LAYER FOR SUBLIMABLE SURFACE,
Abstract
The work is devoted to the problem of the calculation of a laminar boundary layer near sublimable axially symmetric blunt body, moving at a great supersonic speed. There are obtained equations and boundary conditions of the problem. The high temperature in boundary layer causes the presence of chemical reactions. The method of calculating the stationary flow near the critical point of a blunt axially symmetric sublimable body, whose temperature and pressure satisfy either the condition of phase transition, or condition of evaporation is presented. The assumption as to the stationarity of the flow is justified by the following considerations. It is possible to present a special body, which in sublimating repeats its own shape. On the other hand, for any smooth body this assumption has substantiation when the speed of the sublimation is much less than the speed of the oncoming flow. The obtained numerical results for the case of a body consisting of graphite flowed around by oxygen where the chemical reactions occurring in the boundary layer are assumed to be equilibrium.
