Abstract

Objectives: To study the behavior of these parameters following the variation of CH4-H2 fuels in air. Methods/Statistical Analysis: We simulated the behavior of the turbulent methane-hydrogen/air flame, generated by a three-dimensional non-premixed cylindrical combustion chamber. The numerical simulations are carried out using the calculation code CFD “FLUENT”. Mathematical methods were used to solve the Navier-Stokes equations governing the flow phenomenon. Findings: The numerical results are compared and validated with the experimental data. In these conditions, the same parameters considered previously are used in the study of combustion behavior. The parameters characteristics of the flow were characterized such as the axial velocity, the temperature and the mass fraction of the carbon monoxide CO. Application/Improvements: The results show that the variation of the fuel influences the considered parameters. In addition, we confirm that hydrogen is a clean fuel without emitting CO into the environment.
