Eksperimentalno ovrednotenje spremembe intenzivnosti prenosa toplote pri vrenju zaradi staranja vrelnih površin : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoArhar, KlaraStaranje površin pri vrenju pogosto ni obravnavano pri razvoju površin za izboljšan prenosom toplote pri vrenju, čeprav je izjemnega pomena iz aplikativnega vidika. V sklopu naloge smo razvili ... merilno progo za dolgotrajne preizkuse vrenja. Zasnovali smo protokol izvajanja meritev na izdelani merilni progi za ovrednotenje sprememb intenzivnosti prenosa toplote in površinskih lastnosti na časovni skali več stournega obratovanja. Izvedli smo ovrednotenje dolgotrajnega vrenja na neobdelanih površinah iz bakra, aluminija in nerjavečega jekla pri različnih gostotah toplotnega toka. Analizirali smo spreminjanje koeficienta toplotne prestopnosti pri staranju površin in definirali funkcijske odvisnosti spreminjanje koeficienta na bakrenih površinah. Pokazali smo, da se površine, na katerih poteka vrenje, starajo bolj intenzivno kot površine, ki so enako dolgo izpostavljene vrelemu mediju, vendar vrenje na njih ne poteka.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
