Operation characteristics of a disk-type rotating detonation engine

Abstract In the present work, operation characteristics of a disk-type rotating detonation engine (DRDE) with constant chamber area were experimentally studied for various total mass flow rates and wide variety equivalence ratios hydrogen–air mixtures. From direct visualizations, wave was found to propagate near outer wall combustion chamber, regardless mode. For test conditions, single- double-wave modes are observed, depending on ratio mixture. The pressure gain evaluated based one-dimensional model together static measured capillary tube average technique. Although DRDE configuration provided negative all it that single-wave mode superior in terms gain.
