Influence of preferential diffusion in turbulent lean premixed hydrogen-rich syngas spherical flames at elevated pressure
Influence of preferential diffusion in turbulent lean premixed hydrogen-rich syngas spherical flames at elevated pressure
The objective of this work was to investigate the influence of preferential diffusion on flame structure and propagation of lean-premixed hydrogen-carbon monoxide syngas-air flame at elevated pressure using direct numerical simulation (DNS) and detailed chemistry. The physical problem investigated is lean-premixed hydrogen-carbon monoxide outwardly propagating turbulent spherical flame at constant pressure of 4bar and at constant turbulent Reynolds number of 150. It is observed that the local flame structure, heat release rate tangential train rate are strongly altered by preferential molecular diffusion at elevated pressure.

Abstract
The objective of this work was to investigate the influence of preferential diffusion on flame structure and propagation of lean-premixed hydrogen-carbon monoxide syngas-air flame at elevated pressure using direct numerical simulation (DNS) and detailed chemistry. The physical problem investigated is lean-premixed hydrogen-carbon monoxide outwardly propagating turbulent spherical flame at constant pressure of 4bar and at constant turbulent Reynolds number of 150. It is observed that the local flame structure, heat release rate tangential train rate are strongly altered by preferential molecular diffusion at elevated pressure.
