Dynamic behavior and flame acceleration of spherically expanding hydrogen flames under the low-pressure conditions

open access: yesNihon Kikai Gakkai ronbunshu, 2023
To investigate the dynamic behavior and flame acceleration of spherically expanding hydrogen flames under the low-pressure conditions, the deflagration experiments were conducted in a closed combustion chamber. The dynamic behavior of hydrogen flames was

Instabilities and soot formation in high-pressure, rich, iso-octane-air explosion flames - 1. Dynamical structure [PDF]

open access: yes, 2007
Simultaneous OH planar laser-induced fluorescence (PLIF) and Rayleigh scattering measurements have been performed on 2-bar rich iso-octane–air explosion flames obtained in the optically accessible Leeds combustion bomb.

On the small-scale stability of thermonuclear flames in Type Ia supernovae [PDF]

open access: yes, 2002
We present a numerical model which allows us to investigate thermonuclear flames in Type Ia supernova explosions. The model is based on a finite-volume explicit hydrodynamics solver employing PPM.

Two-dimensional cellular burner-stabilized flames [PDF]

open access: yesQuarterly of Applied Mathematics, 1994
We consider the behavior of a premixed flame anchored on a flat burner. For Lewis numbers L > L ∗ > 1 L > {L^*} > 1 , one-dimensional stationary spatially periodic solutions corresponding to stationary one-dimensional cellular flames (rolls ...

Effects of the Unburned-Gas Temperature and Lewis Number on the Intrinsic Instability of High-Temperature Premixed Flames

open access: yesJournal of Thermal Science and Technology, 2011
The effects of the unburned-gas temperature and Lewis number on the intrinsic instability of high-temperature premixed flames under the constant-enthalpy conditions were investigated by two-dimensional unsteady calculations of reactive flows.

Cellular Flame Instabilities [PDF]

open access: yes, 2017
The onset of Darrieus Landau and thermo-diffusive instabilities in an exploding spherical laminar flame is marked by the value of the Peclet number, Pecl, which is dependent upon the Markstein number.
