Propagation of premixed flames in confined channels
The propagation of premixed flames in confined channels is investigated. In the unconfined case, the structure of the flame and the flame speed for the adiabatic planar flame have been numerically obtained and confirmed with the existing theory. It is seen that in the unconfined case, the flame …

DNS of inhomogeneous reactants premixed combustion
… specifically on the interactions of an initially planar flame with field of inhomogeneous reactants. Unsteady and unstrained laminar methane-air flames are studied in one- and two-dimensional simulations to investigate the effects of normally and tangentially (to the flame surface) stratified …

Flame-flow interaction during premixed and stratified swirl flame flashback in an annular swirl combustor
The interaction between a propagating flame and the approach flow is critical to the understanding of boundary layer flashback of swirling flames. In this work, I investigated this interaction during flashback using high-speed luminosity imaging and simultaneous three-dimensional particle image …

A new theory of premixed flames in near-stoichiometric mixtures
In this dissertation, a new model of premixed flames in near-stoichiometric mixtures is derived. Unlike most previous theories, which are valid only for very lean or very rich, i.e. off-stoichiometric conditions, our model remains valid over the entire spectrum of mixture compositions, from lean to …

Modelling of premixed laminar flame propagating in channels
… dynamics of the intrinsically unstable premixed flames propagating in channels is studied by means of numerical modelling in this work. Critical conditions of extinction and the influence of the thermal-diffusive effect on the dynamics of flame propagating in planar channels with cold sidewalls …

Hydrodynamic stability of a premixed flame subjected to transverse shear
Flame instabilities arise intrinsically in combustion systems and have important implication in the operation of engineering devices. The primary intrinsic instability of premixed combustion is caused by thermal gas-expansion, known as the hydrodynamic or the Darrieus-Landau (DL) instability. …
