Analysis on thermodynamic performance of partially-fueled pulse detonation engine

Ideal partially-fueled detonation cycle model was established based on Ficket-Jacobs cycle. It is shown that partial fuel filling will cause decrease of total thermal efficiency, which means that this work mode is not adequate to the application of detonation for power output. However, as energy exchange between combustion products and purge gas occurs during the expansion of the detonation products under this mode, it can be used to enhance the propulsive efficiency of PDE.
