TL;DR: In this article, the authors describe measurements of global turbulent consumption speeds, ST,GC, of hydrogen/carbon monoxide (H2/CO) mixtures at mean flow velocities and turbulence intensities of 4 ǫ 1 u rms ′ / S L, 0 100, respectively, for H 2/CO blends ranging from 30% to 90% H2 by volume.

TL;DR: In this paper, an experimental and computational investigation of the flame-sheet dynamics of a harmonically excited flame was performed, and it was shown that the flame dynamics are controlled by three key processes: excitation of shear layer instabilities by the axially oscillating flow, anchoring of a flame at the bluff body, and the kinematic response to this forcing.

TL;DR: In this article, the authors describe the response of a swirling premixed flame with constant burning velocity to non-axisymmetric harmonic excitation, showing that wrinkles are excited on the flame that propagate downstream along the mean flame surface at a speed given by U o ǫ cos ψ, where U o is the mean flow velocity and ψ is the flame angle.

TL;DR: In this paper, the response of bluff body stabilized flames to harmonic oscillations was investigated and it was shown that the flame front response at the acoustic forcing frequency first increases linearly with downstream distance, then peaks and decays.

TL;DR: In this paper, an analysis of the response of swirling premixed flames to helical disturbances is presented, where the flow fluctuations have an azimuthal dependence of the form u^i′∞exp(imθ) and m denotes the helical mode number.
