Radiative heat transfer in emitting-absorbing-scattering spherical media

Radiative heat transfer in spherical media that emit, absorb, and scatter radiation is analyzed. Linear anisotropic scattering is considered. The spherical harmonics method is used to solve the equation of transfer. The P-1, P-2, P-3, P-7, and P-11 solutions are presented and their accuracy is discussed. Numerical results presented include the radiant heat fluxes at the inner and outer walls of the spherical enclosure and the distribution of the blackbody emissive power in the medium. The effect of scattering on the transfer of radiant energy is illustrated. (Author)
