摘要: This article numerically analyzes the hyperbolic heat conduction problem in a two-layer composite medium under an initial temperature pulse emanating from the exterior surface of one layer. Reflection and transmission occur when the initial pulse wave impacts the contact surface of the dissimilar material. An interfacial layer with low conductivity and narrow thickness exists at the interface, which is employed to model the thermal boundary resistance at the contact surface, Analysis results indicate Bat the interface resistance significantly influences the wave pattern and strength. The presentation of the wave nature in Be interfacial layer deforms the initial ware feature and induces secondary wavelets behind the reflected and transmitted wave. In addition, the piecewise secondary wavelets become smooth when the interfacial width is very thin. Also examined herein is the effect of conductivity and thickness width of the interfacial layer coupled with variation of Be two-layer properties ratio on the reflection-transmission-combination phenomena.
