Non-stationary heat conduction in one-dimensional chains with conserved momentum
, 2009 The Letter addresses the relationship between hyperbolic equations of heat conduction and microscopic models of dielectrics. Effects of the non-stationary heat conduction are investigated in two one-dimensional models with conserved momentum: Fermi-Pasta-

Multidimensional quasiballistic thermal transport in transient grating spectroscopy [PDF]
, 2015 Transient grating spectroscopy has emerged as a useful technique to study thermal phonon transport because of its ability to perform thermal measurements over length scales comparable to phonon mean free paths (MFPs).

Non-integrability and the Fourier heat conduction law
, 2014 We study in momentum-conserving systems, how nonintegrable dynamics may affect thermal transport properties. As illustrating examples, two one-dimensional (1D) diatomic chains, representing 1D fluids and lattices, respectively, are numerically ...

Non-Fourier heat transfer in a moving longitudinal radiative-convective dovetail fin
Case Studies in Thermal Engineering, 2023 The purpose of this research is to estimate the non-Fourier temperature distribution in dovetail fin. The Cattaneo-Vernotte heat model is utilized to estimate heat conduction behavioral patterns in dovetail fin.

Heat conduction induced by non-Gaussian athermal fluctuations
, 2013 We study the properties of heat conduction induced by non-Gaussian noises from athermal environments. We find that new terms should be added to the conventional Fourier law and the fluctuation theorem for the heat current, where its average and ...
