... and Δ t is the time step. Recently, Cui and Li ( 21 22 23 ) introduced a discontinuous finite element method (DFEM) to solve steady-state radiative heat transfer in semitransparent medium with uniform refractive index. Their numerical results show that the DFEM has good accuracy...

... 1 ) > 0 In this example, the temperature of semitransparent medium is uniform, therefore the temperature gradient is ∂ T M ∕ ∂ x = 0 . Because T W 1 is greater than T M and T W 2 , as shown in Fig. 2 , the axial radiative heat flux...
