Comparison of Numerically Simulated and Experimentally Measured Performance of a Rotating Detonation Engine [PDF]

A quasi-two-dimensional, computational fluid dynamic (CFD) simulation of a rotating detonation engine (RDE) is described. The simulation operates in the detonation frame of reference and utilizes a relatively coarse grid such that only the essential ...

Computational modeling of dynamic injector response in a Rotating Detonation Engine (RDE)

Applications in Energy and Combustion Science
Rotating Detonation Engines (RDEs) are a form of pressure gain combustion (PGC), offering a promising approach to increase the thermodynamic efficiency of a gas turbine combustor by utilizing a detonation-driven combustion process. In most RDEs, fuel and
