Abstract “Flame-street” refers to the interesting combustion phenomenon that a diffusion flame in a narrow channel is separated into a discrete series of flame segments. Although …
The flame dynamics at ultra-lean condition under the synergistic effect of heat recirculation and flow recirculation is experimentally studied in this work. The previously reported …
This work focuses on the diluent influence on stable methane flames in a fused silica micro flow reactor (MFR). Experimental and numerical investigations are performed. The first part …
In this paper, we study the effect of gravity, or buoyancy forces, on the structure of flames propagating in horizontal channels. It is shown that there are two mechanisms for the …
The present work experimentally illustrates and analyzes the ultra-lean flame blow-off dynamics near laminar critical condition under the synergistic effect of heat and flow …
Highly refined simulations of flame/shock interactions (FSI) are performed and analyzed in the context of hydrogen/air combustion in a two-dimensional shock-tube configuration …

A self-excited acoustic instability of laminar premixed flames propagating in an open-ended tube with a length of 700 mm and a radius of 10 mm was simulated by solving the reacting …
In this paper we present a numerical study of the impact of heat losses and the differential diffusion effect on the flame-acoustics interaction, for flames propagating from the open to …
A joint experimental and numerical investigation of turbulent flame anchoring at externally heated walls is presented. The phenomenon has primarily been studied for laminar flames …
