Assessment of Bray Moss Libby formulation for premixed flame-wall interaction within turbulent boundary layers: Influence of flow configuration

Recent developments in DNS of turbulent combustion

“…The chemistry of methane has motivated many works [21, 27, 41, 42, 50, 52, 54, 56, 61, 62, 68, 74, 77, 82, 84, 88-90, 92, 93, 96, 97, 101, 103, 107, 110, 113, 114, 118, 119, 123, 133, 134, 138, 145, 155, 156, 163, 169, 176, 182, 184, 189, 207, 211, 217, 220, 222, 223], also hydrogen [32, 38, 43, 60, 69, 70, 78, 79, 81, 90, 95, 97-99, 102, 105, 106, 109, 117, 120, 124, 126, 127, 129, 132, 136, 154, 160, 171, 172, 174, 181-183, 185, 193, 195, 204, 209, 214, 218, 224-229], heavy fuel [37,38,53,66,88,100,108,140,145,151,162,170,180,197,203,221,[230][231][232], syngas [66,114,166,181,212,215,216] and very recently ammonia [97]. Models were discussed from DNS within RANS [64,112,113,128,189,233] and LES context [32,37,46,51,65,67,77,94,…”

Energy Integral Equation for Premixed Flame-Wall Interaction in Turbulent Boundary Layers and its Application to Turbulent Burning Velocity and Wall Flux Evaluations

“…The newly derived energy integral equation for premixed FWI in flat plate TBL has been validated using three-dimensional DNS of a turbulent V-shaped flame interacting with an isothermal inert wall in a channel flow configuration. A detailed discussion on the numerical implementation of the DNS database including the validation of the non-reacting channel flow solution can be found elsewhere [15,16] . Only a brief discussion is provided here.…”

“…To date, most analyses on premixed turbulent combustion have been conducted for flames without any wall effects, and recent advancements in experimental diagnostics [2][3][4] and computational simulations [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] have enabled insightful analyses of FWI for turbulent premixed com-bustion. These analyses provided valuable insights into the flame structure and flow dynamics [2,8,12,20] , wall heat flux [2][3][4][5]7,[20][21][22][23][24] , reactive scalar gradient [3,6,7,11,[14][15][16][24][25][26] , kinetic energy [9,13,27] , turbulent scalar flux [10,27] and displacement speed [13,…”

“…Bruneaux et al [21,29] pioneered the computational analysis of FWI in a channel flow configuration but under constant density assumption for unsteady conditions. Alshaalan and Rutland [22,27] , Gruber et al [23] , Ahmed et al [15,16] and Jiang et al [19] analysed oblique wall flame-quenching (OWQ) of turbulent V-shaped premixed flames due to their interaction with isothermal inert walls within TBLs under statistically stationary state using three-dimensional Direct Numerical Simulations (DNS). Recent experiments [3,4] also analysed OWQ of turbulent V-shaped premixed flames in TBLs.…”

“…These studies used the experimental data to assess the performances of the FSD and mean reaction rate models in the near-wall region [3] . Recently, Ahmed et al [15] also assessed the Bray-Moss-Libby (BML) based modelling framework in the context of OWQ of V-shaped premixed flames in TBLs using DNS data. A semi-analytical derivation by Zhao et al [20] demonstrated that the flame speed and wall heat flux are closely linked during flame quenching in a configuration where the flame impinges on an isothermal cold surface.…”
