The effect of a nonlinear scattering gray medium on the radiative intensity by integral moment method

The integral moment method is proposed to solve radiative intensity in nonlinear scattering gray medium. In this paper, this proposed method was to deal with the anisotropic scattering, emitting and absorbing media with different optical depths, orders and boundary conditions. This method was validated by the data from literature. The radiative intensities with high directional resolution at any point can be given by the present method. It is found that the scattering phase function has little effect on the radiative intensity for thin optical thickness, for example, 0.1. It is also found that there is a largest radiative intensity for the nonlinear scattering gray medium with the largest forward scattering capability, and the smallest one with the largest backward scattering capability at the top and bottom boundary.
