Experimental study on the mean flow behind EBMC flameholder

In order to study the flow fields behind the edge blowing mixture curtain (EBMC) flameholder, the detailed near-wake flow behind the EBMC flameholder and the V-gutter flameholder was measured by using 2D cross-correlation on-line PIV in a low speed wind tunnel. The effect of the dynamic parameters and the direction of the jet on the flowfield of the novel flameholder was also investigated. It was revealed that the time-averaged flow field of the EBMC flameholder was similar to that of the V-gutter flameholder, while the jet enlarged the recirculation zone and it increased the turbulence intensity and mass flow rate of the recirculation zone, which would benefit the combustion. It was also found that the momentum ratio of the jet to the main flow was a primary dynamic parameter that affected the flow field of the novel flameholder.
