Velocity-temperature correlation in premixed flame

Transition from pulled to pushed fronts in premixed turbulent combustion: Theoretical and numerical study

“…The decay rates of TWs with K > K min > K KPP are associated with the j À -branch given by Eq. (38), similarly to the pulled TW in the KPP case.…”

“…As predicted by Clavin and Williams [35] and Bray and Libby [36], experimentally discovered by Moss [37] and by Yanagi and Mimura [38], and documented in a number of subsequent experimental and direct numerical simulation (DNS) studies reviewed elsewhere [39], Eq. (2) yields wrong direction of turbulent scalar flux in many weakly turbulent flames, where the gradient ofc and the turbulent flux ofc have the same sign.…”

Thermal radiation properties of turbulent lean premixed methane air flames

“…Many others [11][12][13][14][15][16][17][18] have used this flame configuration. Many of these studies involved temperature and velocity measurements [11][12][13][14]16]. Some studies have involved visualization of flame surfaces and integral length scales of wrinkling [15].…”

Intermittency and Conditional Velocities in Premixed Conical Turbulent Flames

“…Measurements of scalar-velocity correlation in conical flames were reported in the studies of Moss (1980) and Yanagi and Mimura (1981). Moss (1980) obtained the correlations by monitoring simultaneously the LDA signal and the Mie scattering from Ti0 2 or AI 2 0 3 seed particles.…”

“…Moss (1980) obtained the correlations by monitoring simultaneously the LDA signal and the Mie scattering from Ti0 2 or AI 2 0 3 seed particles. Yanagi and Mimura (1981) used a combined thermocouple and LDA technique. The results from both studies are consistent with the co-called counter gradient diffusion for turbulent scalar transport.…”
