Abstract

Theoretically, a Rotating Detonation Engine (RDE) has higher thermal efficiency than a conventional gas turbine engine. In addition, RDE has a potential to shroten the combustuion chamber volume and makes it possible to be a simple strucuture. In order to practicalize RDEs, the optimum propellant injection configurations is necessary for steady combustion and high engine performance because it has a significant role for filling sufficient mixing layers in the combustion chamber. However, CFD analysis are usually done with premixed propellant, whereas experimental investigations are limited in terms of injector configulations. In this work, the slight difference of propagation states of detonation waves due to an increase in the number of fuel holes was not observed. Also, we shows a transiton state of detonation waves with a narrow oxidizer slit, and discuss the phenomenon.
