TWO-DIMENSIONAL RADIATIVE HEAT TRANSFER IN

A Monte Carlo code that simulates radiative heat transfer in participating media for two-dimensional and axisymmetric geometries has been developed. Arbitrary two-dimensional Cartesian and axisymmetric geometries, and the dif-fuse and specular reflectance of surfaces as a complex function of incident angle are able to be modeled. This work has added the ability to simulate the absorption and emission of the combustion gases: CO2, H2O, CO, CH4, SO2 and NO. The theory of gas radiation and the formulation and implementation of the model are presented. Several aspects of the simulation are verified by numerical solutions, comparison to published results and experimental data. The accuracy and utility of the simulation are demonstrated by comparison to other one-dimen-sional solutions for radiative heat transfer in combustion gases and by comparison to experimental data for an axisymmetric furnace
