Hybrid regularized Lattice-Boltzmann modelling of premixed and non-premixed combustion processes

Matching Conditional Moments in PDF modelling of non-premixed combustion

The rate of generation of fluctuations with respect to the scalar values conditioned on the mixture fraction, which significantly affects turbulent non-premixed combustion processes, is examined in the paper. Simulation of the rate in major mixing model is investigated and the derived equations can assist in selecting the model parameters so that level of conditional fluctuations is better repr...

Extended flamelet model for LES of non-premixed combustion

Simulation of Lean Premixed Turbulent Combustion

There is considerable technological interest in developing new fuel-flexible combustion systems that can burn fuels such as hydrogen or syngas. Lean premixed systems have the potential to burn these types of fuels with high efficiency and low NOx emissions due to reduced burnt gas temperatures. Although traditional scientific approaches based on theory and laboratory experiment have played esse...

Cyclic flame propagation in premixed combustion

In experiments of hot surface ignition and subsequent flame propagation, a puffing flame instability is observed in mixtures that are stagnant and premixed prior to ignition. By varying the size of the hot surface, power input, and combustion vessel volume, it was determined that the instability is a function of the interaction of the flame, with the fluid flow induced by the combustion product...
