Abstract
A numerical study of the formation of the temperature field and the melting rate of a layer of ice scattering radiation vertically located on an opaque substrate during radiation heating has been carried out. To solve the radiation part of the problem, a modified method of average fluxes is used, taking into account the volume absorption and scattering of radiation into the medium, as well as the selective nature of the radiation source. Anisotropic scattering radiation is taken into account by the method of expanding the scattering indicatrix in a series according to Legendre polynomials. The effect of the spectral volumetric properties of ice on the melting and temperature increase of the non-irradiated side is presented. Comparison of calculation results with experimental data demonstrates satisfactory agreement. The proposed method for taking into account anisotropic scattering does not show any significant difference from isotropic scattering.
