Mode-locked rotating detonation waves: Experiments and a model equation [PDF]

open access: yesPhysical Review E, 2020
Direct observation of a Rotating Detonation Engine combustion chamber has enabled the extraction of the kinematics of its detonation waves. These records exhibit a rich set of instabilities and bifurcations arising from the interaction of coherent wave fronts and global gain dynamics.
