The mathematical model is based on physically realistic assumptions and it is solved by the finite-difference method, implicit alternating directions method. This method has great accuracy and is of second order with regard to the approximation of time and space. The initial conditions are an analytical solution of the heat conduction equation in the case of the contact of two semi-infinite media. The latent heat of fusion incorporated into the equation for the specific heat capacity of metal, and temperature dependent thermophysical properties of all materials in the system mould-casting-core-chill, enables us to accurately numerically represent the flange solidification, which is casting and a common example in foundry practice. The simulation of the directional solidification is a modern and scientific way of pointing to casting points in which the defect occurrence is possible, and how to prevent them using the chill</dc:description><dc:description xml:lang="sl">Predstavljena sta matematični model in numerična simulacija usmerjenega strjevanja prirobnice iz rdeče svinčeve medenine. Podlaga matematičnega modela so realne fizikalne predpostavke, model pa je razvit z metodo končnih razlik, implicitno metodo z alternativno smerjo. Ta metoda je zelo natančna in je drugega reda glede na približek časa in prostora. Začetni pogoji so analitične rešitve enačbe za toplotno prevodnost za primer kontakta dveh semineskončnih medijev. Latentna talilna toplota, ki je uporabljena za specifično toplotno kapaciteto kovine in termofizikalne lastnosti vseh materialov v sistemu forma - litje - jedro - kokila omogočajo, da se numerično modelira strjevanje prirobnice, torej litje, kar je splošen primer dela v livarni. Simulacija usmerjenega strjevanja je moderna metoda, da se znanstveno opredeli mesta ulitka, kjer lahko nastajajo napake in kako te napake s kokilo preprečiti</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-LSRDY63C"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-LSRDY63C" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-LSRDY63C/2ef785ce-01ca-41ca-bafe-71ffd841b69a/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">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-LSRDY63C/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-LSRDY63C" /></ore:Aggregation></rdf:RDF>
