Origin of effective non-Fourier heat conduction phenomena in heterogeneous materials
A volume-averaging derivation shows that two-component materials obeying Fourier's law at the microscale produce a Jeffreys-type macroscopic heat equation with a dynamic over-diffusive timescale and finite-sample size dependence.
