Equation of motion of a phonon gas and non-Fourier heat conduction
Journal of Applied Physics, 2007Heat conduction in solids is due to the motion of the phonon gas. A more general description of the heat transport in solids includes consideration of the mass, pressure, and inertial force of the phonon gas. The mass of the phonon gas refers to the equivalent mass of its energy based on Einstein’s mass-energy relation.

Analysis of Non-Fourier Conduction Waves from a Reciprocating Heat Source
Journal of Thermophysics and Heat Transfer, 1997The temperature proe les that result when a point heat source is swept back and forth along a rod in which heat travels at e nite speed are examined. Green’ s functions are used to solve the hyperbolic heat equation for cases in which the source speed is half, equal to, and double, the natural thermal wave speed of the rod material.

Dynamical Governing Equations of Non-Fourier Heat Conduction
2015Thermal energy has its corresponding equivalent mass according to Einstein’s mass–energy equivalence, which is termed as thermomass. The thermomass theory established the continuous governing equation for the non-Fourier heat conduction. The mass balance equation of thermomass gives the energy conservation equation while the momentum balance equation ...

Nicht-Fouriersche Wärmeleitung (non-Fourier heat conduction)
2000Es handelt sich um eine Form der Warmeleitung, zu deren Beschreibung die Konstitutive Gleichung — als Materialgleichung — in Form des Fourierschen WArmeleitungsgesetzes in der WArmeleitungsgleichung nicht ausreicht, weil bestimmte EfFekte damit nicht erfast werden konnen.

New Interpretation of Non-Fourier Heat Conduction in Processed Meat
Journal of Heat Transfer, 2005This work uses the “dual phase lag” (DPL) model of heat conduction to offer a new interpretation for experimental evidence of non-Fourier conduction in processed meat that was interpreted previously with hyperbolic conduction. Specifically, the DPL model combines the wave features of hyperbolic conduction with a diffusion-like feature of the evidence ...
