Velikostna separacija vodnih kapljic na superhidrofobnih površinah : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoJereb, Samo, 1998-Slaba omočljivost superhidrofobnim površinam ponuja številne aplikacije, kot so samočistilnost, antikorozivnost in preprečevanje zmrzovanja. V okviru magistrske naloge smo obravnavali uporabo ... superhidrofobnih površin za velikostno separacijo kapljic. Razvili smo teoretični model za napoved velikosti kapljice pri prehodu skozi odprtino tanke folije. Rezultate smo primerjali z eksperimentalno določenimi velikostmi kapljic pri prehodu skozi lasersko izrezane odprtine tanke bakrene folije z lasersko strukturirano in hidrofobizirano površino, ki je izkazovala superhidrofobne lastnosti. Pri velikosti odprtin od 1,2 do 2 mm, kjer je velikost kapljic pri prehodu manjša od kapilarne dolžine kapljevine, je odstopanje teoretično napovedane velikosti premera od izmerjene velikosti manj kot 20 %. Z zmanjševanjem velikosti odprtin se natančnost teoretičnega modela povečuje in doseže manj kot 10% odstopanje v primeru odprtin s premerom manjšim od 1,5 mm. Predstavili smo tudi metodologijo za dinamično velikostno separacijo kapljic z uporabo bakrenih mrežic s superhidrofobnimi površinami, ki so bile pripravljene z jedkanjem površine ter nanosom hidrofobnih snovi. Velikostna separacija kapljic je odvisna od mejne velikosti kapljic, pri kateri kapljice še lahko prehajajo skozi odprtine mrežice. Eksperimentalno smo določili mejno velikost kapljic za mrežico z odprtinami velikosti 2,46 mm, ki se nahaja med 4,2 in 4,5 mm.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
