Abstract:Unsteady flow fields are generated in gas turbines due to interactions between rotating and stationary components. Increased understanding of unsteadiness and its effect on blade heat transfer is crucial to thermal durability predictions for turbine components. This study examines unsteady pressure, heat transfer, and film cooling on a rotating high-pressure turbine stage using experimental and unsteady computational tools. Comparisons between experimental and computational results identify several key element… 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.
