Abstract:Free-surface vortex formation is one of the undesirable hydraulic phenomena that may occur at intakes during the dewatering reservoir. This research is meant to investigate the effect of waves on formed vortices in vertical intakes numerically by applying STAR-CCM + software. The simulation was conducted to model the free surface and turbulence by volume of fluid and large eddy simulation methods, respectively. Sensitivity analysis was undertaken on different mesh sizes to select appropriate mesh dimensions. T… 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.
