Description

Large Eddy Simulations, with the Conditional Moment Closure as the combustion sub-model, have been used to capture localised extinction, flame lift-off, and whole flame blow-off for simple geometries like jet flames (Movies 1 and 2 below), swirl-stabilised recirculating flames of natural gas (Movies 3-6), and spray flames (Paper "Spray_LESCMC_PalermoSept2012.pdf". The work is described fully in the following papers: (i) Garmory, A. and Mastorakos, E. (2011) Capturing localised extinction in Sandia Flame F with LES-CMC.
