Heat diffusion at the boundary of stratified media: homogenized temperature field and thermal constriction (Q597910)

The authors investigate the steady and transient heat diffusion in stratified materials with layers running parallel to the heat flux direction. The steady solution is separated into a homogenized transfer in series with a constriction matrix term. In semi-infinite transient case, some simplified models are obtained from asymptotic expansions. These results could be useful in understanding experimental temperature field analysis for thermal non- destructive evaluation methods.
