Numerical investigation of turbulent lean premixed hydrogen-carbon monoxide combustion at elevated pressures
Numerical investigation of turbulent lean premixed hydrogen-carbon monoxide combustion at elevated pressures
This work describes analyses of impact of chemical kinetic mechanisms on species mass fraction distributions and effects of preferential diffusion on flame structure and propagation of turbulent lean premixed high hydrogen content syngas flames using direct numerical simulations (DNS). The present study has two principal aims. The first is to investigate the impact of detailed chemical kinetic model employing in DNS on prediction of species mass fractions of lean premixed HHC hydrogen-carbon monoxide syngas turbulent flame at elevated pressure. The second aim is to study the preferential diffusion (non-unity Lewis number) effect on flame structure and propagation of lean premixed HHC syngas turbulent flame at elevated pressure.

Abstract
This work describes analyses of impact of chemical kinetic mechanisms on species mass fraction distributions and effects of preferential diffusion on flame structure and propagation of turbulent lean premixed high hydrogen content syngas flames using direct numerical simulations (DNS). The present study has two principal aims. The first is to investigate the impact of detailed chemical kinetic model employing in DNS on prediction of species mass fractions of lean premixed HHC hydrogen-carbon monoxide syngas turbulent flame at elevated pressure. The second aim is to study the preferential diffusion (non-unity Lewis number) effect on flame structure and propagation of lean premixed HHC syngas turbulent flame at elevated pressure.
