Numerična simulacija pretoka fluida in prenosa toplote v grelniku dizelskega goriva : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoGaberšček, MatijaV podjetju Hidria d.o.o. (podružnica Tolmin) je v razvojni fazi grelnik dizelskega goriva. Ena od razvojnih zahtev kupca je bila tudi numerična simulacija pretoka nafte skozi grelnik. Zanimala nas je ... temperaturna in tlačna razlika med vhodnim in izhodnim stanjem goriva pri pretoku skozi grelnik. Numerični preračun smo naredili v programu ANSYS CFX. 3D model smo za mreženje in preračun pripravili v PTC Creo 3.0 modelirniku. Robne pogoje smo definirali v CFX-Pre modulu ANSYS-a. Rezultate numerične simulacije smo primerjali z izmerjenimi. Meritve smo izvedli v prostorih podjetja. Preračun in meritve so bile izvedene za tri časovno neodvisne (stacionarne) pretoke. Napako numeričnega preračuna smo ustrezno ovrednotili. Rezultate smo grafično predstavili v modulu CFX-Post. Prikazali smo hitrostno, temperaturno in tlačno stanje. Toplotni izkoristek grelnika je pri največjem pretoku znašal 90 %. Iz rezultatov in njihovega grafičnega prikaza smo izpostavili možnosti za izboljšave numeričnega modela in konstrukcije grelnika.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
