Ray tracing method combined with Hottel's zonal method is used to establish radiation transfer model in anisotropic scattering media. The transmission progress of radiation intensity in the absorbing, emitting and anisotropically scattering medium is divided into two sub-progresses: emitting-attenuating-reflecting progress and absorbing-scattering progress. For the medium with both surfaces being semitransparent and mirror-like, radiative transfer coefficients are developed. Energy equation of transient coupled radiation and conduction heat transfer is solved by the fully implicit control-volume method. In this paper, it needs only to disperse spatial location while spatial solid angle is integrated directly. On this basis, effects of conduction-radiation parameter, spectral refractive index and scattering phase functions etc., on the temperature field and radiative heat flux field within an anisotropic scattering medium are examined. The results show that: the linear part in linear or nonlinear scattering phase function can produce great difference of the temperature field and radiative heat flux field between anisotropic scattering medium and isotropic scattering medium.
