Effect of pressure on counterflow H2-air partially premixed flames

A computational investigation of high-pressure hydrogen-air partially premixed flames (PPF) was presented to characterize the effect of pressure on flame structure, and to examine the relevance of reaction limits in the context of H2/air PPF. Increasing pressure reduced the flame speed and the diffusive losses of H-atoms out of the rich premixed zone, induced transition from the first to the second reaction limit in this zone, and caused this …
