We solve the coupled system of dynamical and thermodynamical equations describing a liquid by truncating the Fourier series. The solutions of the simplified system tend toward the Lorenz attractor in phase space for large enough temperature gradients. The numerical solutions offer an insight into the order of temperature, flow, and characteristic time, typical for convection in a closed container</dc:description><dc:description xml:lang="sl">Prispevek opisuje preprost model naravne konvekcije v valjasti geometriji. Reševanja sklopljenega sistema sistema diferencialnih enačb, ki opisujejo gibanje in toplotne tokove tekočine, se lotimo s Fourierjevo metodo in obdržimo čim manj členov. Rešitve poenostavljenega sistema v faynem prostoru težijo k Lorenzovem atraktorju, če je temperaturni gradient dovolj velik. Rešitve, ki jih poiščemo numerično, dajo občutek za temperaturne gradiente, velikosti tokov in časovno skalo, na kateri pride do sprememb</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-S4RA3DQF"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-S4RA3DQF" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-S4RA3DQF/5942503d-8097-49d7-b384-ed3a06d09f0f/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">Društvo matematikov, fizikov in astronomov</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-S4RA3DQF/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-S4RA3DQF" /></ore:Aggregation></rdf:RDF>
