Conservative Implementation of LES-CMC for Turbulent Jet Flames

The objective of the present work is to validate a large eddy simulation (LES) approach that has been coupled with a conditional moment closure (CMC) method for the computation of turbulent diffusion flames. Contrary to earlier work, we use a conservative
