NONUNIFORM ABSORPTION OF THERMAL RADIATION OF LARGE SEMI-TRANSPARENT PARTICLES AT ARBITRARY ILLUMINATION OF THE POLYDISPESE SYSTEM
Following from: Radiative transfer problems in nature and engineering
The disperse systems of separate spherical particles or droplets randomly positioned in vacuum or gas are considered in this section. It is assumed that the average distance between the particles is large in comparison with their size and the wavelength of the external thermal radiation. In this case, one can employ the radiation transfer theory to calculate the radiation field in the medium and absorption of the radiation by particles. In such calculations, the particles are usually assumed to be isothermal and the volume distribution of the absorbed radiation power inside the particles is not considered (Viskanta and Mengç, 1989; Dombrovsky, 1996; Viskanta, 2005).
