Abstract:Održivost približno stalnog stepena korisnog dejstva Kaplanove turbine, pri relativno velikoj promeni pada, posledica je promenljive geometrije obrtnog kola turbine. Zavisnost ugla zakretanja lopatica obrtnog kola od otvora između lopatica sprovodnog aparata, predstavlja kombinatorsku karakteristiku turbine. Tačnost ostvarivanja zadate kombinatorske karakteristike, od velike je važnosti za ekonomičnu i pravilnu eksploataciju turbine, odnosno agregata kao celine. Zbog navedenih razloga posebna pažnja posvećena … 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.
