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.

Non-Fourier Heat Conduction Analysis with Temperature-Dependent Thermal Conductivity [PDF]
ISRN Mechanical Engineering, 2011 As a first endeavor, the one- and two-dimensional heat wave propagation in a medium subjected to different boundary conditions and with temperature-dependent thermal conductivity is studied. Both the spatial as well as the temporal domain is discretized using the differential quadrature method (DQM). This results in superior accuracy with fewer degrees

Continuum Modeling Perspectives of Non-Fourier Heat Conduction in Biological Systems [PDF]
Journal of Non-Equilibrium Thermodynamics, 2021 Abstract The thermal modeling of biological systems is increasingly important in the development of more advanced and more precise techniques such as ultrasound surgery. One of the primary barriers is the complexity of biological materials: the geometrical, structural, and material properties vary in a wide range.
