A self-similar premixed turbulent flame model

Numerical Simulation of a Premixed Turbulent V-Flame

Turbulent premixed combustion is a major active research topic in combustion science. A number of computational studies have focused on idealized configurations to aid in interpreting flame dynamics observed in the laboratory, including one-dimensional strained flames, two-dimensional vortex/flame interactions and limited three-dimensional direct numerical simulations. In this paper, we present...

Application of a Flame Dictionary Method in Turbulent Premixed Flame Modeling. Construction of a Flame Dictionary

|The construction of a ame dictionary of ame speeds and preheat thicknesses for a given reaction will be discussed. Once the entries of the dictionary have been established, they can be accessed by researchers and programmers to be used in diierent combustion applications. An application of the ame dictionary for turbulent combustion in a circular cylinder is given. Chemical reactions are often...

Proper Orthogonal Decomposition Analysis of a Turbulent Swirling Self-Excited Premixed Flame

Simulations of edge-flame propagation in turbulent non-premixed jets

Ignition, flame propagation and stabilisation have been simulated and analysed in a turbulent jet of non-premixed methane and air. The first order Conditional Moment Closure (CMC) turbulent combustion model was fully coupled with a Reynolds-Averaged Navier Stokes (RANS) flow simulation. A CMC model was developed to account for spark ignition. The over-prediction of turbulent flame propagation w...

Active Control for Statistically Stationary Turbulent Premixed Flame Simulations

The speed of propagation of a premixed turbulent flame correlates with the intensity of the turbulence encountered by the flame. One consequence of this property is that premixed flames in both laboratory experiments and practical combustors require some type of stabilization mechanism to prevent blow-off and flashback. The stabilization devices often introduce a level of geometric complexity t...
