These computational studies examine transient, reactive compressible flow phenomena associated with the pulse detonation engine or PDE. Simulations of the pulsejet, a related device that involves deflagrations rather than detonations, has also been performed. The present emphasis explores magnetohydrodynamic (MHD) augmentation of PDE performance, as well as fundamental numerical simulations of detonation instabilities.

The PDE is an intermittent combustion engine that relies on unsteady detonation wave propagation for combustion and compression elements of the propulsive cycle.

The schematical configuration of a typical PDE engine, highlighting major features.

One emphasis in these studies focuses on use of high resolution numerical methods and simplified modesl to explore reactive and magnetohydrodynamic (MHD) flow phenomena and performance associated with a range of alternative propulsion devices. These include MHD-augmented Pulse Detonation Rocket Engine (PDRE) concepts and the Pulse Detonation Rocket-Induced MHD Ejector (PDRIME) Concept.
