Determination of the thermal conductivity and thermal diffusivity of solids by unilateral sounding of the surface

  • 30 Accesses

Abstract

The article analyzes the possibility of determining thermophysical characteristics by nondestructive unilateral sounding of a flat surface. Curves are presented for selecting the optimum regime of the experiments in dependence on the dimensions of the sounded body.
