Numerical simulations were used to characterise the non-linear response of a turbulent premixed flame to acoustic velocity fluctuations. The test flame simulated was the bluff body …
Turbulence in low Karlovitz number premixed flames is strongly affected by small-scale combustion heat release. At low Karlovitz number conditions, flame-normal thermal …

In order to experimentally study whether or not the density ratio σ substantially affects flame displacement speed at low and moderate turbulent intensities, two stoichiometric …
Recently, a simple model for evaluating turbulent scalar flux in premixed flames was developed and validated using six experimental data sets obtained from flames stabilized in …
The present work aims at modeling the entire convection flux ρ u W¯ ρuW in the transport equation for a mean reaction rate ρW¯ ρW in a turbulent flow, which (equation) was recently …

Reynolds averaged numerical simulation (RANS) of a turbulent partially premixed flame is performed using a presumed probability density function (Pdf) approach. The mixture …
Unresolved fluxes in turbulent diffusion flames are investigated by introducing the specific volume to analyze the effects of density variations. Unresolved fluxes are found to be related …
