Modeling Thermodynamic Trends of Rotating Detonation Engines
James Koch, J. Nathan Kutz
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…

Mode-Locked Rotating Detonation Waves: Experiments and a Model Equation
James Koch, Mitsuru Kurosaka, Carl Knowlen +1
Direct observation of a Rotating Detonation Engine combustion chamber has enabled the extraction of the kinematics of its detonation waves. These records exhibit a rich set of inst…
