The objective of this paper is to simulate turbulent flow and heat transfer in industrial porous burners. Transport equations are written in their time-and-volume-averaged form and a volume-based statistical turbulence model is applied to simulate the intra-porous turbulence generation. Combustion is modeled via a simple closure. Preliminary testing results indicate that a substantially different flow pattern is obtained depending on the model used. In addition, for high inlet flow rates or high excess air, the flame front moves towards the exit of the chamber.
