Three-dimensional modeling for prediction of wall fires with buoyancy-induced flow along a vertical rectangular channel

This paper presents results on the steady rate of turbulent burning along a vertical rectangular channel in which a buoyancy-induced draft develops. Four different combustion models are implemented in a parabolized formulation of the three-dimensional conservation equations. The model based on a finite volume method includes the effects of natural convection, diffusion, viscosity, gravitational forces, and chemical reactions with energy release. Predictions of the flow held structure and the temperature field are compared for different combustion models and wall fire conditions.
