Heat Conduction Beyond the Fourier Law

The Fourier law correctly describes heat transport in most practical macroscopic problems. However, for heat transfer in rapid processes, heat transport on micro- and nanoscales, and heat transfer in materials with an internal structure (porous media and biological tissues), other models are required that take into account nonlinear effects, as well as temporal (memory) and spatial nonlocality. Such models are considered in this review, including models with time lag, phonon and thermodynamic models, as well as models based on differential equations in fractional derivatives.

Automated summary

In this review, models beyond the Fourier law are explored for heat transport in rapid processes, micro- and nanoscales, and in materials with internal structures. These models consider nonlinear effects, time lag, and spatial nonlocality, including fractional derivatives in differential equations.
