Notes:
In this article we present a theoretical and experimental study of the multiple scattering of a plane thermal wave between a two-layer subsurface cylinder and the material surface. The thermal wave is generated at the surface of an opaque material by a modulated extended laser beam. First we study the multiple scattering of the thermal wave produced by a single conducting cylinder with arbitrary thermal properties. Then, we present a model of the multiple scattering of the wave produced by the two-layer cylinder and the surface. We calculate the surface temperature for two extreme cases of layering: (i) a coating air layer and (ii) a highly conducting coating. Measurements performed with an infrared radiometry photothermal technique on a calibrated set of samples are presented. They validate our models for the homogeneous layered cylindrical conductors. It is demonstrated that the most direct application of this study is the quantitative analysis of the thermal contact resistance (or the characteristics of a coating layer) in a fiber reinforced composite. © 2001 American Institute of Physics.
