摘要：
The problem of melting a layer of ice with bubbles containing radiation-absorbing gas was carried out using a numerical method. The problem statement is radiation-conductive heat exchange in a semitransparent two-phase medium that selectively absorbs radiation with a first-order phase transition. The radiation transfer equation was solved by a modified mean flux method, taking into account a wide range of optical properties of the two-phase medium and the radiation source. The melting rate and growth of non-irradiating boundary depending on various optical parameters of the medium are calculated. The significant influence of anisotropic scattering and strong absorption of radiation by gas on the heating and melting of the ice layer is shown.
