They convert mechanical energy into fluid pressure and back into mechanical torque. Simulation of such machines still requires highly skilled engineers, use of advanced simulation tools and advanced simulation approach … despite the availability of modern simulation tools with well suited graphical user interface (GUI) and numerical techniques. The paper presents recent activities and progress on simulation of hydrostatic machines – in particular, the axial piston pump and the radial hydraulic motor. Despite that these machines have been designed and produced by Poclain for decades, there are still (design) features and phenomena not being investigated in detail or never being simulated. The simulation advancements mainly refer to the application of complicated kinematic motion, fluid properties, physics to consider as well as mesh and numerical algorithm techniques. In this paper, the focus is given on modelling of advanced fluid properties (e.g. compressibility, cavitation etc.). Fluid with such advanced properties is used in fluid flow simulation. Numerical approach has been performed by means of computational fluid dynamic (CFD) within the environment of Siemens Simcenter Star-CCM+. The anticipation of cavitation has been possible by implementation of existing »full cavitation model«</dc:description><dc:description xml:lang="sl">Hidrostatični stroji so naprave, ki prenašajo energijo s pomočjo tlaka tekočine, najpogosteje olja ali vode. Delujejo na principu hidrostatike (Pascalov zakon). Simulacija takšnih strojev še vedno zahteva visoko usposobljene inženirje, uporabo naprednih simulacijskih orodij in napreden simulacijski pristop kljub razpoložljivosti sodobnih simulacijskih orodij z dobro prilagojenim grafičnim uporabniškim vmesni- kom in numeričnimi tehnikami. Prispevek predstavlja dejavnosti in napredek pri simulaciji aksialne batne črpalke. Čeprav te stroje podjetje Poclain načrtuje in proizvaja že desetletja, še vedno obstajajo področja, ki niso podrobno raziskana. Napredek pri simulaciji se nanaša predvsem na uporabo zapletenega kinematičnega gibanja strojnih delov, naprednih fizikalnih lastnosti tekočin in tudi tehnik mreženja ter numeričnih algoritmov. V tem članku se osredotočeno na modeliranje naprednih lastnosti tekočin (stisljivost, kavitacija). Numerični pristop je izveden s pomočjo računalniške dinamike tekočin (CFD) v okolju Siemens Simcenter Star-CCM+. Napovedovanje kavitacije je možno z implementacijo obstoječega »polnega modela kavitacije«</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-88A8MXHS"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-88A8MXHS" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-88A8MXHS/4c08d66b-b029-485b-9fa3-6f42e01c982c/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-88A8MXHS/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-88A8MXHS" /></ore:Aggregation></rdf:RDF>
