Coupled conductive radiative transfer in CO2 with narrow band statistical model and Monte-Carlo simulation

This paper describes an approach in order to determine the radiative source term and the temperature fields in a coupled conductive and radiative transfer. We consider an emitting and absorbing gas (carbon dioxide) enclosed between two horizontal and parallel reflecting plates. The medium is in local thermodynamic equilibrium (LTE). Only radiative and conductive exchanges are considered. An implicit finite difference technique is used to solve the energy conservation equation, and the narrow band statistical model (NBSM) with the Monte Carlo method (MCM) are used for simulation of radiative transfer equation in a coupled manner. This study of coupled conductive-radiative shows many phenomenons: The interaction radiation conduction in an emitting and absorbing gas is sensitive to the molar fraction of gas and the emissivities of walls.
