Formation of detonation in rotating channels
Doklady Physics, 2010308 For estimating the possibility of detonation initia tion during rotation, we considered the gasmixture flow inside and outside the rotating elliptic cylinder included in the circular cylinder. The values of critical parameters at which the detonation is formed were determined.

Analysis of waves dynamics in a rotating detonation combustor fueled by kerosene
The Physics of FluidsThe wave dynamics play a crucial role in the operation characteristics of the rotating detonation engine. We conducted numerical simulations of a rotating detonation combustor (RDC) using multicomponent reactive Navier–Stokes equations coupled with a ...

Numerical Investigation of Rotating Detonation Engines
46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010Rotating detonation engines (RDE’s) represent an alternative to the extensively studied pulse detonation engines (PDE’s) for obtaining propulsion from the high efficiency detonation cycle. Since it has received considerably less attention, the general flow-field and effect of parameters such as stagnation conditions, combustion chamber length, and fuel

Performance Characterization of a Radial Rotating Detonation Combustor with Axial Exhaust
Journal of Engineering For Gas Turbines and PowerThis experimental study characterizes the performance of a radial rotating detonation combustor (RDC). An aerospike nozzle for rocket propulsion has been integrated into the center of the combustor, although the same combustor could also be coupled ...

Rocket rotating detonation engine flight demonstrator
Aircraft Engineering and Aerospace Technology, 2016Purpose Today’s modern liquid propellant rocket engines have a very complicated structure. They cannot be arbitrarily downsized, ensuring efficient propellants’ mixing and combustion. Moreover, the thermodynamic cycle’s efficiency is relatively low.

Analytical study of rotating detonation and engine operating conditions
The Physics of FluidsIn this paper, the mechanism of rotating detonation is analytically discussed using a two-dimensional sheet model. Two ratios are employed in this discussion: the ratio of the sonic point width to the detonation front width, and the ratio of the ...
