Modeling of mean flame shape during premixed flame flashback in turbulent boundary layers
Direct numerical simulations of freely-propagating premixed flames in the turbulent boundary layer of fully-developed turbulent channel flows are used for a priori validation of a new model that aims to describe the mean shape of the turbulent flame brush during flashback. Comparison with the DNS da...
Direct numerical simulation of laminar flame-wall interaction for a novel H2-selective membrane/injector configuration
Direct numerical simulations are performed to investigate the transient processes of laminar flame-wall interaction and quenching near a porous, permeable wall and compared against a reference case of a non-porous impermeable wall. A boundary condition formulation that models species (hydrogen in th...
Direct numerical simulation of premixed flame boundary layer flashback in turbulent channel flow
Direct numerical simulations are performed to investigate the transient upstream propagation (flashback) of premixed hydrogen–air flames in the boundary layer of a fully developed turbulent channel flow. Results show that the well-known near-wall velocity fluctuations pattern found in turbulent boun...

Direct numerical simulation of hydrogen flames at atmospheric and pressurized conditions
Turbulent flame-wall interaction: a direct numerical simulation study
A turbulent flame–wall interaction (FWI) configuration is studied using three-dimensional direct numerical simulation (DNS) and detailed chemical kinetics. The simulations are used to investigate the effects of the wall turbulent boundary layer (i) on the structure of a hydrogen–air premixed flame, ...
