On the determination of laminar flame speed from low-pressure and super-adiabatic propagating spherical flames

Proceedings of the Combustion Institute, 2019
Abstract The outwardly propagating spherical flame (OPF) method is popularly used to measure the laminar flame speed (LFS). Recently, great efforts have been devoted to improving the accuracy of the LFS measurement from OPF. In the OPF method, several assumptions are made.

Premixed flame propagating into a narrow channel at a high speed, part 1: Flame behaviors in the channel

Combustion and Flame, 1985
Abstract This paper deals with the transient behavior of a flame flowing into a narrow channel from a chamber filled with a propaneair mixture. The flame was observed through direct or schlieren high speed photography, and at the same time the arrival at the entrance and exit of the channel were detected by ion gaps.

Image intensification with high-speed videography for flame propagation studies

SPIE Proceedings, 1990
In the past, analysis of flame propagations within a spark ignition engine combustion chamber has been analyzed with pressure diagrams. These pressure diagrams have helped to develop the geometry within the combustion chamber. Photographing or electronically imaging the flame propagations are very important in the visualization of combustion ...

Multiple speeds of flame edge propagation for Lewis numbers above one

Combustion Theory and Modelling, 2005
Edges of diffusion flames in a counterflow burner are examined numerically for Lewis numbers greater than unity. When the speed of propagation is plotted against Damköhler number for a range of Lewis numbers a fold bifurcation is observed. It is shown that there exist stable positively and negatively propagating edges for some Damköhler number and ...
