Thermal Behavior of Perfect and Imperfect Contact Composite Slabs Under the Effect of the Hyperbolic Heat Conduction Model

This work studies the heat transfer mechanisms during rapid heating of twolayer composite thin slabs from a macroscopic point of view using the hyperbolic heat conduction model. The composite slabs consist of two thin metal layers which may be in perfect or imperfect thermal contact. The effects of parameters such as the two films’ thickness ratio, thermal conductivity ratio, heat capacity ratio, thermal relaxation time, and iInterfacial heat transfer coefficient on the thermal behavior of the composite slabs are investigated.
