Abstract:Acoustic dissipation studies were undertaken using a subscale cold-flow rocket motor model to determine the effect of purely geometric variables on the acoustic performance leading to axial mode combustion instability. Cold air served as the working fluid to simulate the internal flow and to obtain a critical nozzle throat. By using interchangeable parts, it was possible to vary the nozzle throat diameter and to simulate the geometry of a cylindrical-bore grain at various motor burn times. The model was acoust… 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.
