UNSTEADY STATE DESTRUCTION OF GLASS-LIKE MATERIALS IN A SUPERSONIC GAS,
Abstract
An approximate analytical solution was obtained for the problem of unsteady destruction of homogeneous glass-like materials in the region of the critical point (line) at constant (or slightly changing) conditions in the external flow. There is a clear expression for the rate of destruction of a material and the dependence of the surface temperature on time in the form of a quadrature. It was shown that the rate of destruction is determined by the surface temperature of the material and barely depends upon the rate of heating the surface. For comparatively low surface temperatures up to 2300K there is a 'sublimation' character of destruction (the degree of gasification is close to one) and removal does not occur in the liquid phase. The results of theoretical calculations are compared with experiments. (Author)
