TL;DR: In this paper, the authors studied a Type Ia supernova explosion using large-scale three-dimensional numerical simulations based on reactive fluid dynamics with a simplified mechanism for nuclear reactions and energy release.

TL;DR: In this article, the results of numerical simulations of cellular detonations generated by using numerical noise as a source of initial fluctuations imposed on a strong planar shock propagating through the reactive medium are reported.

TL;DR: In this paper, a unified theory of turbulence-induced DDT is presented, which describes the mechanism and conditions for initiating detonation both in unconfined chemical and thermonuclear explosions.

TL;DR: An analytical model to describe DDTs is developed and a general analytical theory of tDDT in unconfined systems is presented, which explains the behavior of fast turbulent flames that become unstable, produce shocks, and can transition to detonations.

TL;DR: In this article, large-scale numerical simulations, in conjunction with experimental work conducted at the National Institute for Occupational Safety and Health?s Gas Explosion Test Facility, were performed to address four specific problems: flame acceleration and deflagration-to-detonation transition (DDT) in obstructed channels containing a stoichiometric methane-air mixture.
