TL;DR: Observation de transport de chaleur ultrarapide dans des couches minces d'or sous irradiation laser femtoseconde
Abstract: We have observed ultrafast heat transport in thin gold films under femtosecond laser irradiation. Time-of-flight (from-pump back-probe) measurements indicate that the heat transit time scales linearly with the sample thickness, and that heat transport is very rapid, occurring at a velocity close to the Fermi velocity of electrons in Au.

TL;DR: In this paper, the authors construct an analytical model to describe the dynamic response of a laminar premixed flame stabilized on the rim of a tube to velocity oscillation, and obtain a time-domain differential equation describing the relationship between the velocity perturbation and the heat release response over the entire frequency range.

TL;DR: In this article, a review of the thermal wave theory and its application in the microscopic two-step model is presented. And the authors show that the energy equation may be reduced to that governing the heat transport through the metal lattice.
Abstract: This work contains three major components: a thorough review on the research emphasizing engineering applications of the thermal wave theory, special features in thermal wave propagation, and the thermal wave model in relation to the microscopic two-step model. For the sake of convenience, the research works are classified according to their individual emphases. Special features in thermal wave propagation include the sharp wavefront and rate effects, the thermal shock phenomenon, the thermal resonance phenomenon, and reflections and refractions of thermal waves across a material interface. By employing the dual-phase-lag concept, we show that the energy equation may be reduced to that governing the heat transport through the metal lattice in the microscopic two-step model
