Single-phase Stefan problem in selectively absorbing medium

详细

The thermal state of a translucent selectively absorbing medium was studied by the methods of numerical simulation at different values of the optical properties of boundaries and heat transfer from the left surface in approximation of one-phase Stefan problem. The temperature fields and densities of resultant radiation fluxes as well as the thermal state of the left boundary and dynamics of layer reduction in the melting process were analyzed. The processes of phase transition in a flat layer of selective and gray absorbing media and emitting media were compared, and their fundamental differences were shown.
