Design and testing of a hydrogen–oxygen pre-detonator for rotating detonation engines
CEAS Space JournalAbstract Rotating Detonation Engines (RDEs) have the potential to significantly increase the performance of liquid-propellant rocket engines. Besides, they are also a promising improvement for gas turbine combustors. Therefore, there is a rapidly growing interest world-wide into this technology.

Modeling thermodynamic trends of rotating detonation engines [PDF]
Physics of Fluids, 2020 The formation of a number of co- and counter-rotating coherent combustion wave fronts is the hallmark feature of the Rotating Detonation Engine (RDE). The engineering implications of wave topology are not well understood nor quantified, especially with respect to parametric changes in combustor geometry, propellant chemistry, and injection and mixing ...

Comparative analysis of alternative fuels in detonation combustion [PDF]
, 2016 Detonation combustion prominently exhibits high thermodynamic efficiency which leads to better performance. As compared to the conventionally used isobaric heat addition in a Brayton cycle combustor, detonation uses a novel isochoric Humphrey cycle which

Thermonuclear explosions of rapidly rotating white dwarfs - II. Detonations [PDF]
, 2009 Context: Superluminous type Ia supernovae (SNe Ia) may be explained by super-Chandrasekhar-mass explosions of rapidly rotating white dwarfs (WDs). In a preceding paper, we showed that the deflagration scenario applied to rapidly rotating WDs generates ...
