Numerical simulation of melting of scattering ice in a single-phase Stephan problem

Abstract

Abstract A numerical study of the formation of the temperature field and the melting rate of an ice layer scattering radiation, located on an opaque substrate during radiation heating was carried out. To solve the radiation part of the problem, a modified mean fluxes method was used, taking into account the volume absorption and scattering of radiation into the medium, as well as the selective nature of the radiation source. The effect of the spectral volumetric properties of ice on the melting and temperature increase of the non-irradiated side is shown. Comparison of calculation results with experimental data shows satisfactory agreement.
