... relaxation time magnetic field rotation two-temperature The classical dynamical theory of coupled thermoelasticity which was introduced by Biot [ 1 ] was then extended to generalized theory of thermoelasticity by Lord and Shulman [ 2 ] and Green and Lindsay [ 3 ]. These theories predict the speed...

...Chunjian Ni; Jayathi Y. Murthy A sub-micron thermal transport model based on the phonon Boltzmann transport equation (BTE) is developed using anisotropic relaxation times. A previously-published model, the full-scattering model, developed by Wang, directly computes three-phonon scattering...

... relaxation times are accounted for. Scatterings by different mechanisms are treated individually, and the creation and/or destruction of phonons due to scattering is implicitly taken into account. The proposed method successfully predicts exact solutions of phonon transport across a gallium arsenide film...

...Bao Yang Thermal conductivity equations for the suspension of nanoparticles (nanofluids) have been derived from the kinetic theory of particles under relaxation time approximations. These equations, which take into account the microconvection caused by the particle Brownian motion, can be used...
