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

An adaptive pseudo-spectral method for reaction diffusion problems [PDF]
The spectral interpolation error was considered for both the Chebyshev pseudo-spectral and Galerkin approximations. A family of functionals I sub r (u), with the property that the maximum norm of the error is bounded by I sub r (u)/J sub r, where r is an

Two-dimensional cellular burner-stabilized flames [PDF]
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 ...

Flame Enhancement and Quenching in Fluid Flows [PDF]
We perform direct numerical simulations (DNS) of an advected scalar field which diffuses and reacts according to a nonlinear reaction law. The objective is to study how the bulk burning rate of the reaction is affected by an imposed flow.

The effects of unburned-gas temperature and heat loss on the diffusive-thermal instability of premixed flames were studied by two-dimensional unsteady calculations of reactive flows, based on the diffusive-thermal model equation, under the conditions of ...
