Numerical modeling of the influence of thermal protection materials on characteristics of conjugate heat and mass transfer with spatial flow around blunted bodies

The three-dimensional problem of conjugate heat and mass transfer upon the motion of a spherically blunted cone at various angles of attack along a set trajectory is theoretically explored. Thermal protection materials, including carbon materials with high heat-conducting properties, conventional carbon fiberreinforced plastic coatings, and promising nondestructible ceramic materials, are analyzed. It is shown that the application of the latter makes it possible to preserve the initial geometry of the body and to attain a considerable temperature decrease in the coating surface upon the development of new materials with high thermal conductivity.
