The solutions of pure radiative and combined radiative and conductive heat transfer within a L-shaped enclosure are presented. The enclosure contains a mixture of pulverized carbon particles, CO{sub 2}, and N{sub 2}. Three different types of problems are solved: homogeneous radiative properties, nonhomogeneous radiative properties, and combined conduction-radiation problem with nonhomogeneous radiative properties. To obtain solutions for these problems, the YIX method is used. The YIX quadrature uses piecewise constant interpolation of the integrands. To handle the L-shaped enclosure, an ad hoc approach of searching the struck surface node in the line-of-sight is developed. The general approach of handling any arbitrary complex geometry is briefly described. A single point, implicit, quasi-Newton scheme is used to solve the energy equation when both the radiation and conduction heat transfer modes are present. The quasi-Newton works well for a wide range of dimensionless conduction-radiation parameter except when the parameter is less than 0.2, i.e., radiation is the dominant heat transfer mode.
