The study was performed in two parts: first the observation of flow transformation at temporal stationary changes of the air foil shape was performed, and the second part of the analysis focused on the transformation of the flow at periodic time-pulsating airfoil deformations. With the help of the computer-aided visualization method, structural flow changes were investigated, i.e. variations of the wake frequency response and respective amplitudes depending on the airfoil pulsation frequency. Results show that periodic changes of the airfoil shape have an affect on the flow structure along and behind the airflow, i.e. the amplitude and frequency of the wake, and the location of a separation point. There may exist possibilities for adaptive flow kinematics variation along and behind the airfoil"},{"@xml:lang":"sl","#text":"V polnorazvitem zračnem toku podzvočnega vetrovnika je bila z uporabo računalniške vizualizacije ter metode digitalnega procesiranja serije posnetkov izvedena analiza kinematike toka vzdolž deformljivega profila (NACA 4416) spremenljive oblike pri hitrostnih razmerah Re=1000. V prvem delu raziskave je bila izvedena študija preoblikovanja strukture toka ob profilu pri ustaljenih spremembah oblike profila, v drugem delu pa smo se osredotočilina opazovanje sprememb struktur toka pri periodično utripajoči obliki profila. Z metodo računalniške vizualizacije so bile raziskane strukturne tokovne spremembe v vrtinčni sledi v odvisnosti od frekvence zbujanja geometrijske oblike profila. Rezultati kažejo, da periodične spremembe oblike profila vplivajo na tokovno strukturo vzdolž profila oziroma na njeno frekvenco in amplitudo ter na položaj točke odlepljanja na opazovanem profilu. Pojavlja se možnost prilagodljivega spreminjanja tokovne kinematike vzdolž profila"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-8ULUIL22","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-8ULUIL22"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-8ULUIL22/9d06be65-9a5a-4592-ad6b-4ad69c384af0/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-8ULUIL22/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-8ULUIL22"}}}}
