The mathematical model, in the form of Navier Stokes equations, based on the additional transport equation for vapour mass fraction inception, propagation and condensation is presented for the mixture's (water - water vapour) properties. A simplified Rayleigh-Plesset equation is used when the phase change is modelled, where the parameters that influence the flow dynamics near the individual spherical bubble, surrounded by the liquid, are considered. Mathematical/physical model is included in the CFD code CFX 5.6. Simulation results are compared with experimental results from the cavitation tunnel, where the tested hydrofoil (blade) was placed</dc:description><dc:description xml:lang="sl">Namen prispevka je predstaviti analizo kavitacijskih tokovnih razmer okoli lopatičnega profila NACA. Predstavljen je fizikalno-matematični model v obliki Navier-Stokesovih enačb, zapisanih za fizikalne lastnosti zmesi voda - para in na podlagi prenosne enačbe za ohranitev mase vodne pare, s katero je bil modeliran nastanek, razsirjanje in izginjanje vodne pare v toku zmesi. Pri modeliranju fazne spremembe je bila uporabljena poenostavljena Rayleigh-Plessetova enačba, v kateri so upostevani parametri, ki pomembneje vplivajo na dinamiko tokovnih pojavov v bližini osamljenega krogelnega parnega mehurčka v obdajajoči kapljevini. Matematično fizikalni model je bil vključen v programski paket CFX 5.6, rezultati pa primerjani z rezultati preizkusa, izvedenega v kavitacijskem tunelu</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-9E19Z9VM"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-9E19Z9VM" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-9E19Z9VM/439ab38a-ceac-48af-b373-24c343b29e5a/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-9E19Z9VM/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-9E19Z9VM" /></ore:Aggregation></rdf:RDF>
