Résumé : To respond to present requirements in terms of efficiency and impact on the environment, a new carburant called bio-hythane, a mixture of natural gas up to 20% hydrogen and up to 50% Carbone dioxide, from the recovery of the waste from households and agriculture, via suitable digesters, have been developed with the aim of reducing polluting emissions and optimization of combustion efficiency. The present numerical study characterizes the bio-hythane-air turbulent flame in a co-flow coaxial burner in order to determine the effects of hydrogen addition and CO2 dilution in the fuel on the velocity profiles, the turbulence intensity and the turbulent kinetic energy. The results in this study are obtained by simulation on FLUENT code and validated by experimental results found by PIV technology. The confrontation between the axial and radial profiles of longitudinal velocity and those of the turbulent kinetic energy simulated and experimental results allowed us to appreciate the numerical model used. These simulations are found to be in very good agreement with available experimental results for different configurations of the flow.
