NUMERICAL SIMULATION OF LAMINAR DIFFUSION FLAME WITH FINITE RATE CHEMISTRY AND VARIABLE PROPERTY FORMULATION
ABSTRACT
A numerical model is used for simulation of a confined axisymmetric laminar jet diffusion flame under normal gravity and pressure conditions to predict the velocity, temperature, and species distributions. An explicit finite difference technique has been adopted for the numerical simulation of reacting flow with finite rate chemistry and variable thermo-dynamic and transport properties. The predictions match well with the experimental results available in the literature. A recirculation of ambient air is observed to extend from the exit plane into the domain adjacent to the wall. Radial velocity is never positive (away from the axis) in the solution domain. High temperature and high CO2 concentration zones are confined to a small radial distance. The H2O distribution shows a similar pattern as that of CO2 distribution. On the other hand, CO is almost absent above 10 cm axial height.
