Thermal transient behaviour of a bi-layer material with a non-plane interface

In this study, we propose studying the behaviour in a transitory regime of a bi-layer material with a non-plane interface. The aim of this paper is to show if a “thermal diode” effect in transient regime can exist, knowing that there are no thermal diode effects in steady-state regime. The question is to know if the response of a system can be modified if the stimulation is changed with the detection at the boundaries of the system. For instance, in the case of a “Flash” experiment where the stimulation represents a heat flux and the detection corresponds to a temperature measurement.
