Abstract

This paper focuses on the analysis of biogas combustion in a stabilized non-premixed flame stabilized combustor using the RSM turbulence model. The numerical analysis of the combustor was performed using Computational Fluid Dynamics. The numerical results of flame temperature, CO, CO2 and NO emissions were compared with experimental data and numerical data of the RNG turbulence model obtained in previous works. To stabilize the flame, a mechanical turbulence generator device with high swirler number (Sn = 2.48) is used, which substantially improves the air-fuel mixing process to obtain a better combustion process and flame stability. According to the numerical results obtained, the RSM model fits more accurately to the data obtained experimentally, maintaining a statistical uncertainty of +/- 5% in all measurement points.
