Using the Lattice Boltzmann Method for the numerical study of non-fourier conduction with variable thermal conductivity [PDF]
Journal of Heat and Mass Transfer Research, 2018 The lattice Boltzmann method (LBM) was used to analyze two-dimensional (2D) non-Fourier heat conduction with temperature-dependent thermal conductivity. To this end, the evolution of wave-like temperature distributions in a 2D plate was obtained.
