Analysis of the flame–wall interaction in premixed turbulent combustion
Journal of Fluid Mechanics, 2018 The present work focuses on the flame–wall interaction (FWI) based on direct numerical simulations (DNS) of a head-on premixed flame quenching configuration at the statistically stationary state.

Cyclic flame propagation in premixed combustion
Journal of Fluid Mechanics, 2013 AbstractIn 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 ...

Unstrained and strained flamelets for LES of premixed combustion
, 2016 The unstrained and strained flamelet closures for filtered reaction rate in large eddy simulation (LES) of premixed flames are studied. The required sub-grid scale (SGS) PDF in these closures is presumed using the Beta function. The relative performances
