Abstract

In this experiment a reacting jet in a vitiated crossflow was studied to determine the effect of jet-to-crossflow momentum ratio on flame stabilization. The jet-to-crossflow momentum ratios tested ranged from J=10 to J=30. The momentum ratio was varied by changing the flow conditions of the propane-fueled jet, while keeping the crossflow conditions constant. Chemiluminescene imaging was used to determine the flame stabilization location for each condition. Analysis of the chemiluminescence images indicated that the turbulent mixing between the jet and crossflow was the controlling parameter for flame stabilization. To further support that the flame stabilization was mixing controlled, heated and unheated jets at equal momentum ratios were compared. CHEMKIN was used to calculate an ignition delay time for each jet in crossflow mixture. A comparison between calculated chemical timescales and flow timescales yielded a similar trend to the experimental results for flame stabilization.
