Abstract
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.
