“…flame propagation statistics for simple chemistry DNS in [21,33] are in agreement with detailed chemistry DNS results in [38,39]; statistical behaviors of scalar gradient obtained from simple chemistry DNS in [24,40,41] are in agreement with detailed chemistry based results in [42][43][44] and [41] respectively). A comparison between References.…”

“…[23] and [42] for reaction rate statistics between simple and detailed chemistry; comparison between References. [21,33] and [38,39] for flame propagation statistics between simple and detailed chemistry; comparison between References. [24,40,41] and [41][42][43][44] for scalar gradient statistics between simple and detailed chemistry) it can be expected that the present findings based on simplified chemistry will be at least qualitatively valid in the context of detailed chemistry based analysis.…”

“…However, such simulations remain extremely expensive and are not yet feasible for parametric studies. Previous work has indicated that displacement speed statistics obtained from three-dimensional DNS with simplified chemistry [14][15][16][17][18][19][20][21][22] are in agreement with those obtained from two-dimensional DNS with complex chemistry [3][4][5][6][7][8][9][10][11][12][13]. In the present study, three-dimensional DNS with simplified chemistry is adopted in order to allow for an extensive parametric study without excessive computational cost.…”

“…The displacement speed is defined as the speed at which the flame surface moves normal to itself with respect to an initially coincident material surface. Statistics of displacement speed for turbulent premixed flames have been studied extensively in previous work based on two-dimensional direct numerical simulations (DNS) with detailed chemistry [3][4][5][6][7][8][9][10][11][12][13] and on three-dimensional DNS with simplified chemistry [14][15][16][17][18][19][20][21][22]. These studies have looked at the effects of local strain rate and curvature effect on S d [13][14][15][16][17][18][19][20][21][22][23][24] and have included the influence of root-mean-square (rms) turbulent velocity fluctuation magnitude u and Lewis number Le [9,15,17,22] on these effects.…”

“…The earliest work in this area investigated two-dimensional configurations using a detailed C1 mechanism [1,2,3,4]. Bell et al [5] produced the first simulation of a turbulent methane flame in three dimensions with moderate-fidelity kinetics using DRM-19, which 20 is a simplified mechanism derived from GRIMech 1.2.…”
