Abstract
Ice layer melting on a vertical substrate heated by a radiation source in the form of a halogen lamp is simulated numerically in a single-phase formulation of the Stefan problem. Ice is presented in the form of a clear, non-scattering, selectively absorbing material with two spectral bands of volume absorption. The computational model takes into account the selective nature of the radiation source. The analysis of calculation results shows the predominant role of incident radiation in the formation of the density field of resultant radiation flux in the medium. Satisfactory agreement between the calculations and experimental data is obtained.
