Researchers generalize Fourier's heat equation, explaining hydrodynamic heat propagation

Fourier's well-known heat equation, introduced in 1822, describes how temperature changes in space and time when heat flows through a material. In general, this formulation works well to describe heat ...

Compatibility of the evolution equation for heat flux in dual-phase-lag and three-phase-lag with the principles of thermodynamics

In this work, we investigate the compatibility with the second law of thermodynamics of certain evolution equations for heat flux which frequently appear in the literature when treating problems of ...

Researchers generalize Fourier's 200-year-old heat equation, explaining hydrodynamic heat propagation

Michele Simoncelli, a Ph.D. student at EPFL, Andrea Cepellotti, a former EPFL student now at Harvard, and Nicola Marzari, head of EPFL's Theory and Simulation of Materials laboratory, have developed a ...
