Flame stabilization regimes for premixed flames anchored behind cylindrical flame holders [PDF]
Proceedings of the Combustion Institute, 2021 The objective of this study is to construct a regime diagram for laminar flames stabilized behind flame holders with respect to the presence of a recirculation zone (RZ), trend of heat loss to the burner, and flow strain and flame curvature effects. This is achieved by varying the radius of the cylindrical flame holder and the mixture velocity between ...
