A hydraulic shape of the gate and characteristics of the hydropower plant flow-passage sytem govern the magnitude of pressure forces acting on the gate structure. Flow conditions at the downstream end of the gate may require adequate air admission. Numerical analysis of hydraulic characteristics has been performed for a vertical leaf gate at different gate openings. The analysis has been performed with Computational Fluid Dynamics (CFD) code using finite volume method. Computational results are compared with results of measurements carried out in a model test rig</dc:description><dc:description xml:lang="sl">Varnostna zapornica je lahko vgrajena na vtoku v tunel, nizvodno od izravnalnika ali pa v sesalni cevi vodne turbine. Hidravlična oblika zapornice in značilke pretočnega sistema hidroelektrarne vplivajo na velikost obremenitev na zapornico. Pretočne razmere dolvodno od zapornice narekujejo potrebo po količini zraka, ki ga moramo dovesti v sistem. Numerična analiza hidravličnih značilk je izdelana za navpično tablasto zapornico pri različnih odprtjih zapornice. Analiza toka je izvrsena s pomočjo standardnih numeričnih metod (metoda nadzornih prostornin). Rezultati izračuna so primerjani z rezultati meritev na hidravlično podobni zapornici v laboratoriju</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-BD08NMWU"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-BD08NMWU" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-BD08NMWU/e644f478-60e1-4edf-ad37-675be4c260f1/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-BD08NMWU/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-BD08NMWU" /></ore:Aggregation></rdf:RDF>
