Dynamics of Laterally Propagating Flames in X-ray Bursts. I. Burning Front Structure [PDF]
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 ...

Flame advection and propagation algorithms [PDF]
We present a simple algorithm for approximating the motion of a thin flame front of arbitrary shape and variable connectivity, which is advected by a fluid and which moves with respect to the fluid in the direction of its own normal. As an application, we examine the wrinkling of a flame front by a periodic array of vortex structures.

Effect of Temperature Conditions on Flame Evolutions of Turbulent Jet Ignition
Turbulent jet ignition technology can significantly improve lean combustion stability and suppress engine knocking. However, the narrow jet channel between the pre-chamber and the main chamber leads to some difficulties in heat exchange, which ...

Flame Propagation on the Surfaces of Rapidly Rotating Neutron Stars during Type I X-ray Bursts [PDF]
We present the first vertically resolved hydrodynamic simulations of a laterally propagating, deflagrating flame in the thin helium ocean of a rotating accreting neutron star.

Regulation of Wages and Hours Prior to 1938 [PDF]
Direct numerical simulations are performed to investigate the transient upstream propagation (flashback) of premixed hydrogen–air flames in the boundary layer of a fully developed turbulent channel flow.

Prediction of hydrogen flame propagation in a channel with exit contraction [PDF]
The propagation of a flame front in a homogeneous and initially quiescent hydrogen-air mixture in a channel with exit contraction is numerically analyzed by means of Computational Fluid Dynamics.

The Theory of Steady, One-dimensional, Laminar Flame Propagation for One-step Chemical Reactions [PDF]
The Theory of Steady, One-dimensional, Laminar Flame Propagation for One-step Chemical Reactions. The present status of the theory of one-dimensional, steady, laminar flame propagation for one-step chemical reactions is reviewed with particular emphasis ...

Premixed flame propagation in vertical tubes
Analytical treatment of premixed flame propagation in vertical tubes with smooth walls is given. Using the on-shell flame description, equations describing quasi-steady flame with a small but finite front thickness are obtained and solved numerically. It
