Abstract
The conventional Zel'dovich-von Neumann-Döring (ZND) detonation theory is modified with two-dimensional velocity vectors to account for the performance and steady-state flow features of a rotating detonation engine. The developed analytical model explains many of the steady-state features of the rotating detonation and its thermodynamics. The generation of swirl is shown to be the primary mechanism of energy transfer.
