Prediction of turbulent mixing in confined co-axial reacting jets
Abstract
A numerical model is presented for simulation of parabolic reacting and nonreacting flows as are present in a coaxial diffusion flame. Solution procedures are defined for the continuum equations of the conservation of mass, momentum, and energy, with account taken of turbulence and reaction kinetics. The continuum equations are discretized and finite difference equations are solved iteratively after linearization. Predictions are generated for the case of a coaxial diffusion flame in a circular duct, and good agreement is demonstrated with experimental data.
