Modeliranje 3D toka Save ob vtoku v kanal Nuklearne elektrarne Krško ter primerjava z meritvami = Modelling the 3D flow in the Sava River at the entrance to the inflow channel of Nuclear power plant Krško and comparison with measurementsRajar, Rudolf ...Zaradi predvidene izgradnje HE Brežice bo gladina Save pri vtoku v dovodni kanal Nuklearne elektrarne Krško (NEK) dvignjena za 3 metre, kar bo spremenilo hidravlične in termične razmere pri vtoku ... hladilne vode v dovodni kanal. Projektna naloga je zahtevala simulacije hitrostnega polja in sprememb vtoka lebdečih plavin v bodočih razmerah, pa tudi toplotnih razmer v celotnem bazenu Brežice. Ker je hitrostno polje v bližini vtoka polno 3-dimenzijsko (3D), saj so vertikalne komponente hitrosti istega reda velikosti kot horizontalne, uporabljeni model PCFLOW3D pa je t. i.kvazi 3D, smo izvedli meritve hitrosti toka v Savi nad jezom v bližini NEK. Pri verifikaciji modela smo ugotovili, da daje dobre rezultate v področju gorvodno od vtoka, v bližini vtoka pa je model sicer še uporaben, rezultati pa so zaradi 3-dimenzionalnih karakteristik toka manj točni. Zato pripravljamo verzijo modela, ki bo uporabna tudi za simulacije polno 3-dimenzijskega toka. Sedanji model je pokazal, da se v bodočih razmerah vnos plavin v dovodni kanal za doslej znano sestavo in koncentracije plavin ne bo bistveno spremenil. Verifikacija toplotnega modula je bila že izvršena v letih 1995 in 1998 z meritvami v bazenu Vrhovo, tako v poletnih kot v zimskih razmerah in je pokazala dobro veljavnost in točnost modela.Source: Acta hydrotechnica. - ISSN 0352-3551 (25, [št.] 43, dec. 2012, str. 71-84)Type of material - article, component part ; adult, seriousPublish date - 2012Language - slovenianCOBISS.SI-ID - 6472545
