An octagonal glass model with a moving piston complementary to a real engine cylinder was applied in the analysis. Good agreement between the measured and simulated patterns of the flow structures and the inlet-valve discharge coefficients was obtained. In general, this study shows that in-cylinder CFD predictions yield reasonably accurate results that help to improve the knowledge of the air-flow characteristics during the intake stroke. CFD therefore represents an effective design tool for developing less-polluting and more efficient internal combustion engines</dc:description><dc:description xml:lang="sl">V prispevku so prikazani rezultati numerične analize - simulacij na osnovi računalniške dinamike tekočin (RDT) in meritev hitrostnega polja v vstopnem sistemu motorja z notranjim zgorevanjem z uporabo laserskega Dopplerjevega anemometra (LDA). V ta namen je bil izdelan stekleni osmerokotni model valja, ki je po geometrijski obliki podoben valju resničnega motorja. Premičen bat je tokovne razmere na modelu se bolj priblizal resničnim razmeram pri pravem motorju. Ugotovljeno je dobro ujemanje izračunanih in izmerjenih rezultatov pri določitvi tokovnih struktur, hitrostnega polja v valju in pri določitvi pretočnega koeficienta v vstopnem ventilu motorja. Raziskava je tudi pokazala,da je mogoče z numerično analizo RDT-jem razmeroma dobro napovedati dogajanje v valju motorja in izboljšati razumevanje pojavov, ki spremljajo polnjenje valja motorja</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-1MGMNL8K"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-1MGMNL8K" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-1MGMNL8K/7ce2f2f8-1e41-4f68-96ad-03cce11ab930/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-1MGMNL8K/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-1MGMNL8K" /></ore:Aggregation></rdf:RDF>
