Power-Law Wrinkling Turbulence-Flame Interaction Model for Astrophysical Flames

, 2014
We extend a model for turbulence-flame interactions (TFI) to consider astrophysical flames with a particular focus on combustion in type Ia supernovae.

The Thermonuclear Explosion Of Chandrasekhar Mass White Dwarfs [PDF]

, 1996
The flame born in the deep interior of a white dwarf that becomes a Type Ia supernova is subject to several instabilities. We briefly review these instabilities and the corresponding flame acceleration. We discuss the conditions necessary for each of the

Modeling of hydrogen-enriched natural gas on flame speed propagation

Journal of Physics: Conference Series
Abstract This study investigates the effects of hydrogen addition on the laminar flame speed of natural gas using computational simulations performed with Cantera. The calculated laminar flame speed of hydrogen-enriched natural gas mixtures was simulated across a range of equivalence ratios (0.6-2) and hydrogen fractions (0-25% by volume)

Hydrodynamic theory of premixed flames propagating in closed vessels: flame speed and Markstein lengths

Journal of Fluid Mechanics
A hydrodynamic theory of premixed flame propagation within closed vessels is developed assuming the flame is much thinner than all other fluid dynamic lengths. In this limit, the flame is confined to a surface separating the unburned mixture from burned combustion products, and propagates at a speed determined from the analysis of its internal ...

Laminar flame speed measurements and laser absorption characterization of high-temperature, premixed ethane–air flames

Applications in Energy and Combustion Science
Laminar flame speed, temperature, and pressure measurements were conducted in high-temperature, spherically expanding ethane–air flames. The experiments were conducted in a shock tube, which allows access to a high-temperature regime previously under ...
