Abstract:A turbofan engine acoustic liner is effective at reducing propagated noise. However, there is room for improving performance or making the liner more compact. Plasma actuators have been shown to be useful flow control devices in a number of fluid flow situations. Combining the plasma actuator (PSJA) and passive liner technologies offers the promise that the attenuation of the acoustic liner can be improved with the addition of the active actuators. The research was divided into two realms: oscillatory flow and… 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.
