Abstract:In this study, a concept of using a synthetic jet for micro-propulsion is introduced. The system has no moving parts and operates based on a periodic process associated with bubble growth and collapse on a micro-heater in a confined chamber. The liquid is propelled through a micro-nozzle located at the chamber exit using the interfacial layer movement between the vapor and liquid phases during the bubble growth. High-speed photography and image processing are used to capture the sequence of bubble ebullition i… 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.
