Effect of interface thermal resistance on thermal wave phenomena in a two-layer composite media

Author(s): Whey-Bin Lor and Hsin-Sen Chu

Abstract:
This article numerically analyzes the heat conduction in a two layers composite media under an initial temperature pulse emanating from the exterior surface of one layer.

The thermal wave model, which allows for both a transient heat flux and a finite speed of propagation, predicts significantly different results with those predicted by the Fourier's diffusion model at small time scale.

The differences between the two heat transfer models diminish with increasing time.

The thermal wave model further demonstrates that the internal reflection and transmission occur at the contact surface of the dissimilar material.

To consider the thermal resistance at the contact interface, an interfacial-layer model (ILM) and a radiation h...
