Problem definicije kavitacijskega števila : diplomska naloga univerzitetnega študijaAndrejka, DamijanPojem kavitacije opisuje pojav in aktivnost mehurčkov v kapljevini, ki zaradi tlačnih razlik prehaja med kapljevinsko in parno fazo. Učinki kavitacije so večinoma nezaželeni - erozija površin, hrup, ... ter hidrodinamične izgube, vendar pojav v zadnjih letih kljub temu na nekaterih področjih izkoriščajo v koristne namene. Tak primer je medicina, ki kavitacijo uporablja za čiščenje težko dostopnih delov, obdelovanju materialov in pri optimizaciji nekaterih procesov. Pri raziskavah pa raziskovalci z različnih področij pripisujejo preveliko pomembnost kavitacijskemu številu, ki naj bi enolično opisalo karakteristike kavitacije. Na merilni postaji smo opazovali pojav kavitacije pri različnih hitrostih toka, temperature in kvalitete medija, ter oblikah kavitirajočega telesa. Pridobili smo grafične in numerične parametre kavitacije in jih primerjali med sabo ob upoštevanju kavitacijskega števila. Z meritvami smo ugotovili, da kavitacijsko število ne popiše intenzivnosti kavitacije enolično, temveč je ta pojav odvisen tudi od oblike telesa, temperature in kvalitete medija, ter hitrosti toka.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
