Abstract
Numerical
simulation of thermal state was performed for semitransparent medium; the
thermal state is formed under impact of incident radiation and convective heat
transfer to the ambient medium. The model takes into account the heat transfer
to the semi-infinite opaque substrate below the layer of semitransparent
material. Computation was performed for governing parameters typical of snow
and ice coating during winter period. Solving the radiative part of problem
uses the modified average flux method. This method takes into account the
dependence of optical properties on the wavelength of incident radiation,
scattering, and reflective properties of the layer boundaries.
