Reproduction and Adaptation of Literature-Derived Modeling: Numerical Simulation of Methane/Hydrogen Non-Premixed Combustion

Abstract

It is crucial to reduce CO2 (Carbon dioxide) emissions to mitigate climate impacts. A viable strategy for this reduction is to wholly or partially replace the use of natural gas with hydrogen, a carbon-free molecule, in the combustion processes of the industrial and residential sectors. In this context, the objective of this study is to investigate the combustion of methane/hydrogen binary mixtures using Computational Fluid Dynamics (CFD). Combustion will be simulated in the vertical non-premixed burner of the Senai CIMATEC Laboratory. To optimize computation time, a 2D axisymmetric model was developed. Fundamental aspects of combustion, including flow velocity, temperature, species formation, fuel consumption, and pollutant emissions, will be analyzed to evaluate the impact of partial methane substitution with hydrogen.
