Three-Dimensional Modeling of Turbulent Burning Along a Vertical Confined Rectangular Channel

Key Points

The model reveals the structures of a steady turbulent diffusion flame under varying flow conditions.
Computations using the Navier-Stokes equations and k-e turbulence model show reasonable agreement with physical measurements.
Natural convection, diffusion, and viscosity were key factors accounted for in the modeling process.
The findings highlight areas for further research to enhance the understanding of turbulent combustion dynamics.

Abstract

Abstract A parabolized procedure is used to model a three-dimensional turbulent wall fires along a vertical confined rectangular channel. In this work, we obtained the structures of a steady turbulent diffusion flame for both forced and buoyancy-induced flows. The system of governing equations consists of the Navier-Stokes momentum, mixture fraction and the k-ε - ag turbulent model. The flame sheet model is used to describe the chemical reaction. The computations based on a finite volume method include the effects of natural convection, diffusion, viscosity, gravitational forces, and chemical reactions with energy release. Comparison between measurements and predictions are shown to be in reasonable agreement and areas requiring further research are selected.
