主　　题：hydro turbine Darrieus-type runner duct side-wall effect turbine performance 

摘      要：A ducted Darrieus-type turbine has been proposed for hydropower utilization of extra-low head less than 2 *** the hydro turbine system,in general,might consist of an intake,runner casing section and a draft tube for higher efficiency operation,it was clarified in previous experiment that there was no need of the side-walls of runner casing section and a draft-tube for keeping the efficiency high in the case of duct with an inlet *** would yield a simplification of the structure of the turbine *** order to reconfirm this result for large-sized turbine with 560 mm×300 mm duct,instead of small-sized one with 400 mm×200 mm duct,the side-wall effect on turbine performance was experimentally investigated for three-or four-bladed *** the present paper,the experimental results are shown with considering flow behaviors in the runner section.
