Abstract

Formation of a temperature field and melting rate of ice vertically located on an opaque substrate and scattering radiation at radiant heating were studied numerically. To solve the part of the problem concerning radiative heat transfer, we used a modified method of mean fluxes, which takes into account volumetric absorption and scattering of radiation in the medium, as well as the selective nature of the radiation source. The influence of spectral volumetric properties of ice on melting and temperature rise of the non-irradiated side is shown. Comparison of calculation results with experimental data shows satisfactory agreement.
