Radiative-convective heat transfer in a flow past an evaporating semitransparent melt film

A conjugate problem of nonstationary radiative-convective heat transfer in a turbulent flow of a mixture of gases with solid particles around a horizontal evaporating semitransparent melt film is numerically solved. The moving film is subjected to intense radiative heating by an external source whose radiation interacts with the gas-particle medium and the film in a bounded spectral range. The temperature fields and velocities in the boundary layer and the film are calculated. The computational results given allow determination of the impact of radiation on heat transfer and film dynamics in the boundary layer-film system.
