摘要：
The effect of variable thermal conductivity and variable refractive index on transient conduction and radiation heat transfer in a planar medium is investigated. Thermal conductivity of the medium is assumed to vary linearly with temperature, while the other thermo-physical properties are assumed constant. The radiative transfer equation and the nonlinear energy equation are solved using lattice Boltzmann method (LBM). The effects of various parameters are studied. The LBM results are compared with those available in literature and a good agreement is found.
