- Аннотация: The non-Fourier effects, such as wave-like temperature propagation and boundary temperature jumps, arise in nanosized systems due to the multiple time and space scales nature ofout-of-equilibrium heat transport. The relaxation to equilibrium occurs in successive time and spacescales due to couplings between different excitations, whose relaxation times have different physicalmeanings and may differ significantly in magnitude. The out-of-equilibrium temperature evolutionis described by a hierarchy of partial differential equations of a higher order, which includes boththe diffusive and wave modes of heat transport. The critical conditions of transition from wave todiffusive modes are identified. We demonstrate that the answer to the question concerning which ofthese modes would be detected by experimental measurements may also depend on the accuracyof the experimental setup. Comparisons between the proposed approach and other non-Fouriermodels, such as the Guyer–Krumhansl and Jeffreys type, are carried out. The results presented hereare expected to be useful for the theoretical and experimental treatment of non-Fourier effects andparticularly heat wave phenomena in complex nanosized systems and metamaterials.
