Effects of stratification on the topology and stretch statistics of turbulent flames, aerodynamically stabilized in a high-velocity-ratio coaxial burner

Applications in Energy and Combustion Science
This study investigates radially stratified, globally lean turbulent propane–air flames, aerodynamically stabilized in a high-velocity-ratio coaxial burner, aiming to assess the impact of imposed equivalence ratio gradients on flame stabilization ...

Flame Structure and Flame–Flow Interaction in a Centrally Staged Burner Featuring a Diffusion Pilot

Aerospace
The pilot flame serves as the primary anchor for global flame stabilization in a centrally staged combustor. In engineering practice, it typically operates in the diffusion mode.

Lewis number effects on edge-flame propagation in lifted turbulent flames

, 2015
Three turbulent lifted slot-jet flames of different fuel Lewis numbers are studied using direct numerical simulation (DNS). To reduce the computational cost, a one-step chemistry model is employed with a mixture-fraction dependent activation energy reproducing the dependence of the laminar flame speed on the equivalence ratio which is representative of

Predicted Thermoacoustic Flame Response at Megawatt Scale in a Near-Stoichiometric Atmospheric Industrial Furnace

Energies
While gas-turbine combustors have received much research attention, the forced response of large atmospheric industrial flames is much less studied. To improve the understanding of thermoacoustic instabilities in industrial combustion systems, the forced

Kinetic Uncertainty in Hydrogen Jet Flames Using Lagrangian Particle Statistics

Hydrogen
Hydrogen-enriched fuel injection in staged gas-turbine combustors is commonly achieved through jet-in-crossflow (JICF) configurations, where flame stabilization is governed by a local balance between flow-induced strain/mixing and chemical reaction rates.

Investigation of Flame Stretch in Turbulent Lifted Jet Flame

Investigation of Flame Stretch in Turbulent Lifted Jet Flame
DNS data of a laboratory-scale turbulent lifted hydrogen jet flame has been analyzed to show that this flame has mixed mode combustion not only at the flame base but also in downstream locations. The mixed mode combustion is observed in instantaneous structures as in earlier studies and in averaged structure, in which the predominant mode is found to ...
