Abstract:
The present research work deals with the turbulent gaseous combustion in cylindrical furnaces.
The turbulent diffusion gaseous combustion is studied numerically by solving the governing
differential equations. Control volume based iterative finite difference technique is used for
solving the differential equations.
The standard two equation 'k-E' turbulence model is employed for turbulence closure. The
combustion kinetics is modeled by Eddy Dissipation Combustion (EDC) model. A two step
chemical reaction model is proposed in accordance with the Eddy Dissipation Combustion
(EDC) model to predict the concentration of carbon monoxide. The predicted results of mixture
fraction, concentration of individual species and temperature are compared with the reported
experimental data and other predictions. A good agreement is obtained with the measurements
except in the developing zone where steep gradients are prevalent. Parameters in combustion
rate equations are adjusted to get this agreement.
