Experimental and numerical study of premixed flame flashback

Direct numerical simulation of premixed flame boundary layer flashback in turbulent channel flow

“…A pioneering paper by Lee & T'ien (1982) reports a two-dimensional numerical simulation of laminar flame flashback in a sidewall quenching (SWQ) configuration and suggests that a pressure-based interaction between the premixed flame and the boundary layer flow is the reason behind a larger computed laminar flame speed in the two-dimensional configuration compared with the one-dimensional case. Subsequent studies by Kurdyumov, Fernandez & Linan (2000) and Kurdyumov et al (2007) and Kurdyumov & Fernandez-Tarrazo (2002) on the boundary layer flashback of laminar two-dimensional flames added more realistic features to the model, such as effects of the fuel species Lewis number, but are still limited to one-step chemical kinetics and to the interpretation that boundary layer flashback is governed by physical processes whose main characteristics are two dimensional. Poinsot, Haworth & Bruneaux (1993) performed a DNS of HOQ in a two-dimensional, pseudo-turbulent reactive boundary layer while Bruneaux et al (1996) studied three-dimensional HOQ of a back-to-back, premixed flame propagating in constant-density turbulent channel flow.…”

Asymmetric hydrogen flame in a heated micro-channel: Role of Darrieus–Landau and thermal-diffusive instabilities

“…They concluded that the sensitivity of the flame to external perturbations 57 that existed in their experiment resulted in a random upper and lower asymmetric flame 58 behaviors. Steady asymmetric flames were also observed by Kurdyumov et al ([6], [7]) in their 59 study of methane/air and propane/air flame propagation. They observed asymmetric stable 60 flames in the upper flammability limits.…”

“…The emphasize in their work was to investigate the flashback limits of the flame in micro-62 scale ( [6], [7]), and the physics underlying the asymmetric behavior of the flame was not 63 discussed in their study.…”

Fuel Flexible Turbine System (FFTS) Program

“…Applying a Damköhler number to FB prediction as a function of fuel composition has been investigated previously in laminar premixed flames by Kurdyumov et al (2007). Their experiments focused on propane and methane in an uncooled tube burner.…”

“…Expanding on the work of Kurdyumov et al (2007) With these assumptions, only the lowest H 2 concentration for which FB occurs needs to be known. This is different from the approach with LBO because combustors designed to operate with NG do not readily FB without significant variation to normal conditions, therefore H 2 must be added before FB occurs.…”
