Kavitacija in kavitacijska erozija v postaji z radialnim tokom : magistrsko delo magistrskega študijskega programa II. stopnje
Žigon, Aljaž
Kavitacija je pojav, ki je posledica padca tlaka vode. Pogosto se pojavlja v hidravličnih strojih, v katerih povzroča vibracije, hidrodinamični upor, spremembo kinematike toka, hrup ter svetlobne ...učinke. Najpomembnejša posledica kavitacije je kavitacijska erozija. Na kavitacijski postaji smo s pomočjo aluminijastih vzorcev preučevali kavitacijo pri povišani temperaturi. S pomočjo mikroskopa smo opazovali erozijo, ki se je pojavila na vzorcih. S pomočjo hitre kamere smo opazovali kolapse mehurčkov ter tako poskušali ugotoviti povezavo med temperaturo medija ter kavitacijsko erozijo. Dobljene posnetke smo nato analizirali s pomočjo programa Matlab. Iz dobljenih rezultatov smo ugotovili, da se kavitacijska erozija spreminja glede na temperaturo medija. Ugotovili pa smo tudi, da je kavitacijska erozija pogojena predvsem z lokacijo implozije mehurčkov.
