Two recent developments in numerical simulation of premixed and partially premixed turbulent flames

Comptes Rendus. Mécanique, 2006
A subgrid scale closure for Large Eddy Simulation of premixed turbulent combustion (FSD-PDF) is proposed. It combines the Flame Surface Density (FSD) approach with a presumed Probability Density Function (PDF) of the progress variable that is used in flamelet chemistry tabulation.

An algorithm for LES of premixed compressible flows using the Conditional Moment Closure model [PDF]

, 2011
A novel numerical method has been developed to couple a recent high order accurate fully compressible upwind method with the Conditional Moment Closure combustion model. The governing equations, turbulence modelling and numerical methods are presented

Effects of Turbulence on the Combustion Properties of Partially Premixed Flames of Canola Methyl Ester and Diesel Blends

Journal of Combustion, 2011
Canola methyl ester (CME) is a biofuel that is a renewable alternative energy resource and is produced by the transesterification of canola oil. The objective of this study was to document the effects of turbulence on the combustion characteristics of ...

Combustion mechanism of propane-air swirling premixed flame near lean flammability limit

Journal of Thermal Science and Technology
This study investigated a premixed propane-air flame in a partially tapered swirl burner. Experimentally, we found that a flame resembling a morning glory flower formed at an equivalence ratio near the lean flammability limit.

Improved combustion stability of biogas at different CO2 concentrations using inhomogeneous partially premixed stratified flames

Global Energy Interconnection
Biogas is a renewable and clean energy source that plays an important role in the current environment of low- carbon transition. If high-content CO2 in biogas can be separated, transformed, and utilized, it not only realizes high-value utilization of ...

Filtered density functions from direct numerical simulation of a reactive jet in cross-flow

, 2010
Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;
