Abstract
In this work, the discrete ordinates approximation of the two-dimensional radiative transfer equation with anisotropic scattering is solved using nodal techniques along with the Analytical Discrete Ordinates Method (ADO Method). The main goal is the treatment of radiation problems in anisotropic media. The complexity of the model is reduced with the application of the nodal technique (integration process) and the one-dimensional transverse integrated equations are then solved by the ADO method, such that the resulting solution is explicit in terms of the spatial variables. The average density radiation is obtained for the case of second order expansion of the scattering law. Numerical results along of the centerline of the domain are presented and compared with results available in the literature with good agreement, in general achieving analogous accuracy based on the division of the domain into smaller number of nodes.
