Experimental and numerical study of the accuracy of flame-speed measurements for methane/air combustion in a slot burner [PDF]
, 2011 Measuring the velocities of premixed laminar flames with precision remains a controversial issue in the combustion community. This paper studies the accuracy of such measurements in two-dimensional slot burners and shows that while methane/air flame ...

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 ...

Stabilization of a premixed laminar flame on a rotating cylinder [PDF]
, 2017 This paper investigates the stabilization of a laminar premixed flame on a rotating cylinder. Experiments and DNS are combined to analyze the effects of rotation on the flow topology and flame stabilization. Both experiment and simulation reveal that the

The influence of turbulence on the structure and propagation of enclosed flames [PDF]
, 1966 Although it has long been established that burning rates can be appreciably increased by turbulence, the actual extent of this increase and the precise mechanism involved are still far from clear.

The Interaction of High-Speed Turbulence with Flames: Global Properties and Internal Flame Structure
, 2011 We study the dynamics and properties of a turbulent flame, formed in the presence of subsonic, high-speed, homogeneous, isotropic Kolmogorov-type turbulence in an unconfined system.

Generation of adverse pressure gradient in the circumferential flashback of a premixed flame [PDF]
, 2016 Circumferential upstream propagation of a premixed flame in a region confined between two concentric tubes is considered. The cold flow in this configuration features rotational motion and the flame is modelled as an interface separating the burned and ...

Variation of turbulent burning rate of methane, methanol, and iso-octane air mixtures with equivalence ratio at elevated pressure [PDF]
, 2005 Turbulent burning velocities for premixed methane, methanol, and iso-octane/air mixtures have been experimentally determined for an rms turbulent velocity of 2 m/s and pressure of 0.5 MPa for a wide range of equivalence ratios. Turbulent burning velocity
