Abstract [en]

Computational fluid dynamics (CFD) analysis on detonations, and the resulting exhaust dynamics are studied. Specifically the analysis seeks to quantify the relative ability of the cycles to refill with unburned air that can be mixed with fuel for pulsed detonation. The relative magnitude of the effects of ignition location, fuel location, and basic tube geometry on this self-aspiration are first investigated in smaller, more time-efficient simulations. From these, additional variables, such as ejectors, and different inlet shapes are tested with the most promising configuration of fuel ignition and overall pipe geometry. These further tests are carried out at scales more comparable to the experimental setups. The results obtained are compared with the previous pulse-jet configurations and known pulse detonation data. Steps are taken toward optimizing a static thrust self-aspirating valveless pulse detonation engine (PDE).
