The numerical analysis was made using software for an approximate solution of a system of conservation law equations. The results yield a comparison of numerically obtained values of the lift coefficient, as well as diagrams of pressure coefficients and velocity vectors on the airfoil, at different angles of attack. The validity of the method of computation was confirmed with a comparison of computed lift coefficient values for the closed trailing edge profile, with experimentally acquired values from literature. It is reasonable to continue the research of flow conditions with the use of the open trailing edge airfoil</dc:description><dc:description xml:lang="sl">Predstavljena je primerjava tokovnih razmer pri obtekanju zraka okoli dvodimenzionalnega profila NACA 4421 z zaprtim izstopnim robom (običajna oblika profila) in novo obliko lopatice z odprtim izstopnim robom. Numerična simulacija je bila narejena s programskim paketom za aproksimativno reševanje sistema parcialnih enačb, ki predstavljajo ohranitvene zakone. Rezultati podajajo primerjavo izračunanih vrednosti vzgonskih koeficientov, ter diagrame tlačnih koeficientov in vektorjev hitrosti na profilu, za različne natočne kote. Pravilnost načina izračuna je bila potrjena s primerjavo izračunanih vrednosti koeficientov vzgona za primer zaprtega profila, z eksperimentalno pridobljenimi vrednostmi iz literature. Rezultati simulacij kažejo, da je smiselno nadaljevanje raziskav izboljšanja tokovnih razmer z uporabo lopatice z odprtim izstopnim robom</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-IP568QZ3"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-IP568QZ3" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-IP568QZ3/2ac8cfb4-bc64-49f5-aa2c-5953ec47e5f1/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 Mariboru, Fakulteta za energetiko</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-IP568QZ3/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-IP568QZ3" /></ore:Aggregation></rdf:RDF>
