Mechanism of deflagration-to-detonation transition in gas
arXiv:2307.05485
Abstract
The deflagration-to-detonation transition on the tip of an elongated flame in a tube is shown to be related to a dynamical saddle-node bifurcation of the inner flame structure leading to a runaway of the pressure in finite time. The comparison with the experiments shows a good agreement.
