Peclet correlation for stability of inverse diffusion flames in methane-air cross flows

Thermal and emission characteristics of a turbulent swirling inverse diffusion flame

“…Inverse diffusion flame (IDF) possesses characteristics of these two types of flame, and therefore can exploit the advantages of both flames in regard to operational safety, pollutant emission and flame stability. These advantages of IDFs and their potential domestic and industrial applications have motivated a number of related experimental and numerical studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

“…Mikofski et al [5] measured the flame lengths of IDFs by examining the position of planar laser-induced fluorescence of hydroxyl radicals, and it was found that IDFs and NDFs are similar in structure. Clausing et al [6] examined the stability characteristics of IDFs and a modified Peclet number was applied to correlate the IDF stability data. Both computational and experimental studies of the preferential diffusion effects on temperature in NDFs and IDFs were carried out by Takagi et al [7].…”

“…The IDFs studied so far were all non-swirling flames [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Swirling flames are becoming important in the combustion community due to the added flame stability and enhanced rate of combustion.…”
