Modeling of the process of heat transfer from a plane heat source of constant strength in thermophysical measurements

Abstract

Consideration is given to the theoretical foundations of the method of nondestructive testing of the thermophysical properties of solid materials subjected to thermal action from a plane heat source of constant strength on a bounded portion of the surface. It has been established that the evolution of the thermal process from a bounded plane heater will be analogous to the evolution of the thermal process in a plane half-space and to the processes in a spherical half-space at high values of time.
