Abstract
An oscillating combustor may support a time-sequenced combustion reaction having rich and lean phases. The rich and lean phases may be determined according to a flame position relative to a diverging fuel jet. The flame location may be modulated responsive to an interaction between applying a constant voltage or charge rate to a fuel stream or flame, and modulating continuity between a conductive or semiconductive flame holder and an activation voltage.
