This study aims to conduct a comprehensive assessment of biogas combustion within the context
of a turbulent diffusion flame, with the goal of deepening the scientific understanding of the physical
and chemical mechanisms governing this type of combustion and improving its efficiency in energy
applications.
The focus of the study is on the combustion of a binary mixture composed of methane and
hydrogen, with an investigation into how different mixing ratios affect flame behavior, stability, and
energy conversion efficiency.
The study includes a detailed analysis of the flame's dynamic and thermal properties, examining
temperature distribution, flow patterns, and mixing characteristics between the fuel and oxidizer
under strong turbulence conditions. The obtained results were compared to experimental data,
showing a highly positive correlation.
The stability of the flame was also evaluated under the influence of different hydrogen ratios (30%
and 40%), given hydrogen's crucial role in enhancing flame speed and increasing temperature.
Environmental performance indicators were also considered by monitoring pollutant emissions
from combustion, particularly nitrogen oxides (NOx), with the aim of proposing clean and
environmentally friendly combustion solutions.
This study can serve as a foundation for advanced mathematical and numerical models to simulate
the complex reactions occurring within turbulent flames, enabling a precise analysis of chemical
reactions and flow fields.
