On the Wave Heat Transfer at Times Comparable with the Relaxation Time upon Intensive Convective-Conductive Heating

Abstract

The behavior of temperature fields in the vicinity of the boundary of a body at nanosecond durations comparable with relaxation time has been studied on the basis of an analytic solution to the problem of a hyperbolic equation for heat conductivity under the obtained conditions for convective-conductive heat transfer. The presence of first-order damped discontinuities in a temperature profile at a finite rate of the propagation of heat perturbations and convexity of the temperature profile in the vicinity of body boundary have been shown. The method of reduction of restoring relaxation time by experimental values of temperature field has been proposed.
