Abstract
In this paper, the numerical results of the study of
a turbulent flame of methane-hydrogen/air generated by a
cylindrical burner are presented. The numerical simulations
are carried out using the CFD code "FLUENT" and
"Gambit" for the meshing process. The finite volume
method was used to solve the Navier-Stokes equations
governing the flow. The coupling of the LES/PDF models is
used to model the turbulence/chemistry interaction in the
system's transport equations. The results of the calculations
are expressed and analyzed in terms of axial velocity,
temperature and mass fraction of carbon monoxide CO. The
results of the numerical calculations are compared and
validated against experimental data. In addition, the same
parameters considered above are used in the study of the
combustion behavior of CH4
/H2
fuels. The obtained results
confirm the fact of considering hydrogen as a clean nonpolluting fuel compared to methane, since it has no carbon
monoxide emissions in combustion products. Besides this
fact, the hydrogen gas velocity in the flame is significantly
higher by comparing it to the methane gas velocity
