Abstract:The critical heat flux of fast transient boiling impacts the safety assessment of nuclear reactor designs. This paper conducted a series of experiments to explore the critical heat flux of saturated water boiling at different heating rates on a platinum wire. The wire is placed in a glass box surrounded by deionized water at saturation temperature. The diameter of wire is 126 μm, and a constant voltage power supply is used. Data is collected at 250k sample/s. A high-speed camera with 50,000 fps is used to reco… 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.
