Abstract

The problem of radiation-conductive heating and subsequent melting of ice in a climatic chamber in a single-phase approximation of the Stefan problem was posed and solved by mathematical modeling methods taking into account a thin water film formed on the irradiated surface. The fields of temperature and density of the resulting radiation flux are obtained, as well as the rate of melting and heating of the non-irradiated ice surface. Comparison of results with experimental data showed satisfactory agreement.

考虑辐射的近似Stefan问题中冰加热和融化的模拟

在Stefan问题的单相近似中，提出了气候室内的辐射传导加热和随后的冰融化问题，并通过考虑在辐照表面形成的薄水膜的数学建模方法进行了求解。得到了辐射通量的温度场和密度场，以及未辐照冰面的融化和升温速率。计算结果与实验数据比较，结果吻合较好。
