Abstract:SUMMARYHere we describe analytical and numerical modiÿcations that extend the Di erential Reduced Ejector= mixer Analysis (DREA), a combined analytical=numerical, multiple species ejector=mixing code developed for preliminary design applications, to apply to periodic unsteady ow. An unsteady periodic ow modelling capability opens a range of pertinent simulation problems including pulse detonation engines (PDE), internal combustion engine ICE applications, mixing enhancement and more fundamental uid dynamic uns… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
