Vpliv termodinamskega učinka na agresivnost kavitacijske erozije : diplomska naloga visokošolskega strokovnega študijskega programa I. stopnje strojništvoPetrič, DavidKavitacija je fizikalni pojav, pri katerem se zaradi lokalnega padca tlaka pojavijo mehurčki, medtem pa temperatura medija ostane približno nespremenjena. V večini primerov so učinki kavitacije ... nezaželeni, ki se odražajo kot hrup, vibracije, erozija, tlačne izgube, toplotne izgube. V sklopu diplomskega dela smo izdelali tlačno posodo, v kateri smo lahko nastavljali poljuben tlak. Tlak smo nastavljali tako, da smo v posodi s pomočjo kompresorja zvišali tlak, nato pa z regulacijskim ventilom nastavljali željene tlačne pogoje. Znotraj tlačne posode se je nahajala manjša posoda v katero smo natočili tekoči dušik in nato v nadaljevanju tudi hladno, ter vročo vodo. Generiranje kavitacije smo ustvarili z ultrazvočno sondo na katero smo namestili vzorec iz aluminija. Vzorec smo po vsakih 12 sekundah v tekočem dušiku, vzeli iz posode, ter ga slikali pod veliko povečavo. Slike so nam služile za nadaljnjo analizo, kjer smo opazovali poškodbe na vzorcu, ki so nastale zaradi kavitacijske erozije. Za obdelavo slik smo si pomagali s programom Inkscape in programom Matlab. S pridobljenimi rezultati smo lahko primerjali agresivnost kavitacije v hladni, ter vroči vodi in v kapljevitem dušiku.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
