This paper describes one- and two-dimensional numerical simulations, with simplified as well as full reaction kinetics, of a single cycle pulse detonation engine (PDE). Focus of the present studies is on 1) the presence of a nozzle extension at the end of the tube, and its effect on performance parameters as well as noise characteristics, 2) critical “spark ignition” energies associated with the initiation of a detonation in the PDE tube, and 3) quantification of performance parameters associated with full kinetics simulations of the PDE and comparison of these data sets with available experimental data. The present simulations demonstrate the ability to predict PDE reactive flow phenomena and associated performance and noise characteristics, and hence have promise as a predictive tool for the evolution of future PDE designs.
