Type Ia Supernova: Burning and Detonation in the Distributed Regime
, 2007 A simple, semi-analytic representation is developed for nuclear burning in Type Ia supernovae in the special case where turbulent eddies completely disrupt the flame. The speed and width of the ``distributed'' flame front are derived.

Ignis: A one-dimensional laminar flame code
SoftwareXLaminar flame codes have an important role in combustion modeling. They can provide a fundamental understanding of flame dynamics and provide a basis for building subgrid scale models in turbulent flow simulations.

The Coherent Flame Model for Turbulent Chemical Reactions [PDF]
, 1977 A description of the turbulent diffusion flame is proposed in which the flame structure is composed of a distribution of laminar diffusion flame elements, whose thickness is small in comparison with the large eddies.

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.

Applications in Energy and Combustion ScienceIn this study, premixed ammonia‒hydrogen‒air mixtures at different pressures (50∼300 kPa), equivalence ratios (0.7∼1.5), and hydrogen concentrations (9∼50.00 %) were centrally ignited in a closed vessel, and the propagation of a spherical flame was ...

Diffusion-controlled combustion [PDF]
, 2001 We devote this brief review to some relevant aspects of diffusion-controlled combustion. After a survey of the conservation equations involved, we shall describe the Burke-Schumann limit, which is applicable when the reaction time at the flame is very ...

Impact of the Nozzle Angles on Counterflow Diffusion Flame to Strain Rate Variations [PDF]
, 2016 The Diffusion laminar combustion of liquefied petroleum gas (LPG) and air is studied experimentally using counterflowing axisymmetric jets. Attributes of this type of burner arrangement for studying laminar combustion are discussed in terms of flame ...

Experimental Investigation of the Continuous Transition of Flame-Spreading near the Blow-Off Limit
Journal of Combustion, 2020 This study investigates the continuous transition from flame-spreading to stabilized combustion near the blow-off limit in opposed forced flow by using expanding solid fuel duct that makes distribution of oxidizer velocity in the axial direction.

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005 The analysis addresses some aspects of the extinction and the structure of diusion flames established by burning of two fuels. This analysis is asymptotically performed presuming one-global-step chemical reactions with large activation energies. By working with fuels with dierent activation energies, the structure is composed by two zones with dierent ...
