Examination of Wave Speed in Rotating Detonation Engines Using Simplified Computational Fluid Dynamics [PDF]

open access: yes
A simplified, two-dimensional, computational fluid dynamic (CFD) simulation, with a reactive Euler solver is used to examine possible causes for the low detonation wave propagation speeds that are consistently observed in air breathing rotating ...

Design and Experimentation of a Premixed Rotating Detonation Engine [PDF]

open access: yes, 2016
Desire for a more efficient air breathing engine has shifted research attention to the Rotating Detonation Engine (RDE). Detonation is a more efficient combustion process than deflagration and provides a pressure gain.

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

open access: yes
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 ...

Thermodynamics of a Rotating Detonation Engine [PDF]

open access: yes, 2013
A practical thermodynamic cycle model of a rotating detonation engine (RDE) is developed for the purpose of predicting performance and understanding flow field behavior. The cycle model is based on a heuristic analysis of a RDE numerical simulation.

Impact of an Exhaust Throat on Semi-Idealized Rotating Detonation Engine Performance [PDF]

open access: yes
A computational fluid dynamic (CFD) model of a rotating detonation engine (RDE) is used to examine the impact of an exhaust throat (i.e., a constriction) on performance.

Modeling Thermodynamic Trends of Rotating Detonation Engines

open access: yes, 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 ...

希釈された炭化水素燃料噴霧中を伝播する二相爆轟に対するEulerian-Eulerianモデル [PDF]

open access: yes, 2023
Research on power generation or propulsive devices based on detonation gained interest in the past two decades. Indeed, detonation-based devices, such as rotating detonation engines (RDE) or pulse detonation engines (PDE), may confer a thermal efficiency
