Displacement speeds in turbulent premixed flame simulations [PDF]

, 2008
The theory of turbulent premixed flames is based on a characterization of the flame as a discontinuous surface propagating through the fluid. The displacement speed, defined as the local speed of the flame front normal to itself, relative to the unburned fluid, provides one characterization of the burning velocity.

Turbulent Flame Speed Scaling for Expanding Flames with Markstein Diffusion Considerations

, 2012
In this work we clarify the role of Markstein diffusivity on turbulent flame speed and it's scaling, from analysis and experimental measurements on constant-pressure expanding flames propagating in near isotropic turbulence. For all C0-C4 hydrocarbon-air mixtures presented in this work and recently published C8 data from Leeds, the normalized turbulent

Stabilization of confined premixed flames in supersonic flows

Applications in Energy and Combustion Science
Achieving stable and efficient combustion in high speed conditions presents significant challenges due to the coupled effects of turbulent mixing, finite-rate chemistry, and short residence times.
