The computational analysis proposed has the objective of validating physical model of radiation chamber inside furnaces. The main phenomena involved are: energy transport, turbulence, mass transport and chemistry reaction. This study can be used by other researchers as a guideline to choose a model that represents adequately the physical phenomena of great industrial interest. In this paper one has used a commercial software called PHOENICS, from CHAM (www.cham.co.uk), to work out the necessary CFD simulations.

The radiation model used in this study was IMMERSOL, which is a proprietary radiation model developed by CHAM. Combustion phenomena were modeled using the 3 gases model, which considers the reaction fuel + oxidant -> product (only 3 species).

Finally, the temperature, velocity and pressure profiles, among others, will be shown throughout the radiation chamber. Hence, this work aims the study of the main physical phenomena that takes place inside the radiation chamber of a general furnace using computational fluid dynamics (CFD) as a tool.
