The purpose of this paper is to demonstrate the effects of thermal expansion, as a result of heat release arising from exothermic chemical reactions, on the underlying turbulent fluid …
Head-on quenching of statistically planar stoichiometric methane-air and hydrogen-air flames has been compared based on a Direct Numerical Simulation (DNS) database. Due …
Three-dimensional direct numerical simulations of V-flames interacting with chemically inert walls in a fully developed turbulent channel flow have been performed under adiabatic and …
The statistical behaviors of mean enstrophy and its evolution during head-on interaction of premixed flames propagating toward a chemically inert flat wall across the turbulent …

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 …
The influence of thermal wall boundary conditions on the behaviour of scalar statistics during flame-wall interaction (FWI) of premixed flames within turbulent boundary layers has …
The bending effect of turbulent flame speed variation (ie, the deviation from the linear increase of flame speed with increasing root-mean-square turbulent velocity fluctuation) has …
The effects of turbulent integral length scale to flame thickness ratio on the bending effect of turbulent burning velocity variation have been analysed based on a three-dimensional …
The influence of fuel Lewis number Le F on the statistical behaviour of wall heat flux and flame quenching distance has been analysed using direct numerical simulation (DNS) data …
