Dynamics of Laterally Propagating Flames in X-ray Bursts. I. Burning Front Structure [PDF]
, 2019 We investigate the structure of laterally-propagating flames through the highly-stratified burning layer in an X-ray burst. Two-dimensional hydrodynamics simulations of flame propagation are performed through a rotating plane-parallel atmosphere ...

Quasi-steady stages in the process of premixed flame acceleration in narrow channels [PDF]
, 2013 The present paper addresses the phenomenon of spontaneous acceleration of a pre-mixed flame front propagating in micro-channels, with subsequent deflagration-to-detonation transition. It has recently been shown experimentally [M. Wu, M. Burke, S.

On the Evolution of Thermonuclear Flames on Large Scales [PDF]
, 2006 The thermonuclear explosion of a massive white dwarf in a Type Ia supernova explosion is characterized by vastly disparate spatial and temporal scales. The extreme dynamic range inherent to the problem prevents the use of direct numerical simulation and ...

Flame Acceleration Enhancement by Distributed Ignition Points
Journal of Propulsion and Power, 2005 This paper reports on the investigation of a novel method for promoting flame acceleration leading to detonation initiation in a tube. A common method used to initiate a detonation wave is via flame acceleration in an obstacle laden tube. Previous studies with fuel-air mixtures have shown that the measured detonation run-up distance, and corresponding ...

Influence of hydrodynamic processes on apparent flame velocity in accidental explosions [PDF]
E3S Web of Conferences, 2023 The main impact factor of an accidental explosion is explosive pressure, the numerical value of which is determined by the magnitude of the apparent flame velocity during explosive combustion of an explosive mixture.
