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.

选择性热源照射下的冰融化

在Stefan问题的单相公式中，数值模拟了在由卤素灯形式的辐射源加热的垂直基板上融化的冰层。冰以透明的，无散射的，选择性吸收的材料形式呈现，具有两个体积吸收光谱带。计算模型考虑了辐射源的选择性。对计算结果的分析表明，入射辐射在介质中最终辐射通量的密度场形成中起着主要作用。计算和实验数据之间获得令人满意的一致性。
