The simulation model has a modular structure, composed of various cooling-system submodels that are interconnected by links. An efficient analysis is possible only when the interactions between the submodels are considered simultaneously. Because of its complexity and the variety of installed devices, a marine cooling system consisting of two or more interconnected cooling circuits is presented. The temperatures in particular parts of the cooling system are maintained through thermostatic valves by mixing or diverting streams of cooling fluid. Due to the change of flow rate through the thermostatic valves, by varying the heat load and connecting or disconnecting any cooled device, a different pipeline configuration occurs. For this reason, a self-adapting algorithm for the flow and pressure-drop calculation across the cooling system is the core of the simulation model. The validation of the presented simulation model indicates good matching of thenumerical predictions with the measured values. The possible application ofsuch a model to the cooling systems of vehicle engines is presented too"},{"@xml:lang":"sl","#text":"V prispevku je predstavljen simulacijski model za analizo prenosa toplote in snovi v hladilnem sistemu motorja v prehodnem rezimu delovanja. Simulacijski model ima modulno sestavo in je sestavljen iz različnih podmodelov hladilnega sistema, ki so med seboj povezani s toplotnimi povezavami. Analizo je mogoče izvesti učinkovito le, če so povezave med posameznimi modeli upostevane sočasno. V prispevku je zaradi svoje zahtevnosti in razlienosti vgrajenih naprav predstavljen model hladilnega sistema za plovila, ki vsebuje dva ali več hladilnih kroznih tokov. Raven temperatur v posameznih delih hladilnega sistema se vzdržuje z uporabo termostatskih ventilov in z mesanjem različnih tokov hladilne tekočine. Različne oblike hladilnega sistema je mogoče doseči sspreminjanjem toka skozi termostatske ventile, s spreminjanjem toplotnih obremenitev ali s priklapljanjem in odklapljanjem različnih hladilnih naprav. Zaradi različnih moznih izvedb pomeni jedro simulacijskega modela prilagodljiv algoritem za izračun tokov in tlačnih padcev v hladilnem sistemu. Iz rezultatov ovrednotenja simulacijskega modela je mogoče ugotoviti dobro ujemanje numerično ocenjenih in izmerjenih vrednosti. Predstavljena je tudi uporaba tega modela na primeru motorja vozil"}],"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-4U6MFFDP","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-4U6MFFDP"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-4U6MFFDP/9c406b10-6b97-4957-8c77-c725e6dd5726/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-4U6MFFDP/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-4U6MFFDP"}}}}
