Résumé

A procedure has been developed for predicting the flow pattern, temperature and concentration distributions and heat flux patterns within furnace chambers coupling the finite difference solution of the fundamental equations of motion and transport of heat and mass with the zone or flux method representing radiative transfer. The radiative properties of the combustion gases have been represented by various models.
Results of the calculation are compared with experimental data from a test furnace. The zone method gave reasonably good predictions of the radiative heat flux on the combustion chamber wall. The predictions by the flux method were relatively poor.
Results of the study to determine the effect of gas "darkness" on the radiative distribution of the furnace wall and the temperature distribution within the enclosure are presented.
Certain procedures are recommended to improve the computational efficiency of the presented solution.
