Abstract
In a non-premixed flame mode of combustion, the fuel and oxidizer react. It began to mix very immediately. The flow rate had slowed due to the mixing. For such modes of combustion, the combustion system’s high turbulence shear layer has been chosen to encourage mixing. ANSYS was used to do the numerical analysis for the parameters mentioned above. By aiding in the air whirling can impact combustor performance by affecting the fuel–air mixing process and creating a recirculation zone that can function as a flame holder. RSM turbulence models were employed in this study. It has been proven to be reliable in this type of study. The numerical data had been backed up by the available experimental results. Carbon dioxide can impact Hydrogen has unique combustion characteristics as compared to hydrocarbons, such as well as a broad flammability range, a low minimum ignition energy, and a fast flame speed. At AFR 50, hydrogen and carbon dioxide were diluted from 0 to 50% hydrogen and carbon dioxide. Investigate thermal emission with this numerical set-up. It has been expanded to include thermal emission at AFR 50 for carbon dioxide and hydrogen dilution, as well as a PPM emission contour.
