Abstract:In this paper, the flow characteristics around rectangular cylinders with different length to height ratios (aspect ratios, AR) of AR1, AR2, AR3 and AR4 are studied using a particle image velocimetry. The Reynolds number (Re) was 7200 in all cases and the results were analyzed in terms of the mean flow characteristics, Reynolds stresses and triple velocity correlations. The separated flow did not reattach for AR1 and AR2 cylinders. The flow topology around the AR2 cylinder showed a massive wake vortex compared… 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.
