Flame structure analysis for turbulent lean premixed spherical flames at elevated pressures
Flame structure analysis for turbulent lean premixed spherical flames at elevated pressures
This paper investigates influence of elevated pressures on flame structure and propagation of lean syngas spherical flames using direct numerical simulation (DNS) and detailed chemistry. The physical problem investigated is lean-premixed hydrogen-carbon monoxide at constant pressure values of p=2bar and 4bar and at constant turbulent Reynolds number of Ret=50, 100 and 150. We have found that elevated pressures significantly influence the formation of highly wrinkled cellular flame structures and also heat release distributions in the thin reaction zone.

Abstract
This paper investigates influence of elevated pressures on flame structure and propagation of lean syngas spherical flames using direct numerical simulation (DNS) and detailed chemistry. The physical problem investigated is lean-premixed hydrogen-carbon monoxide at constant pressure values of p=2bar and 4bar and at constant turbulent Reynolds number of Ret=50, 100 and 150. We have found that elevated pressures significantly influence the formation of highly wrinkled cellular flame structures and also heat release distributions in the thin reaction zone.
