Numerical simulation of radiative-convective heat transfer at streamlining of the semitransparent film of melt

Abstract

Nonstationary radiative-convective heat transfer was simulated at turbulent streamlining of a semitransparent film of melt on a flat plate by the gas mixture and solid particles. The moving film is subjected to intensive radiation heating by an external source radiating within a limited spectral range. The temperature and velocity fields are calculated in the boundary layer and in the film. Calculation results allow determination of the effect of source temperature and film initial heating on dynamics of temperature and velocity fields of the medium in the boundary layer-film system.
