Transient combined heat transfer by radiation and conduction is investigated within a participating nongray planar slab with one surface coated. Anisotropic scattering is included. By the modified ray tracing method, a radiative transfer model is developed and radiative transfer coefficients (RTCs) under specular reflection are deduced. Five spectral bands are used to simulate radiative spectral properties of translucent material. Radiative source term is calculated by RTCs. Transient energy equation is solved by the full implicit control-volume method under the external radiative and convective boundary conditions. The influences of scattering characteristics such as various scattering phase functions and scattering albedo values on the transient thermal behavior are examined. According to numerical results obtained in this paper, it is found that fully backward scattering, fully forward scattering and forward mixed scattering make a great difference in transient temperature distributions and steady-state total heat flux with isotropic scattering case as a reference.
