“…The following observations are made: The majority of the samples feature a stabilization velocity larger than 3SL 0.43 m/s (for = 1 at 7 bar), which was shown to provide an upper bound of the speed of an edge-flame [11,18,[46][47][48]. In previous studies, edge-flame speeds larger than 3SL were only reported for Lewis numbers larger than unity [48] or twin premixed edge-flames [49], which is not the case here.…”
