Abstract:This paper describes the development of a high speed on/off bi-directional check valve. The design was characterized using coupled-physics modelling tools, and a prototype was constructed and tested in the laboratory. The simulated and experimental results were compared. The high speed on/off bi-directional check valve (BDCV) utilizes positive feedback of flow forces and differential port pressure to quickly open and close the primary poppet. The coupled-physics model incorporates mechanical and fluid domains,… 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.
