Optimiranje cevnih mrež z uporabo aditivov : magistrsko deloKrope, AndrejV magistrskem delu je predstavljena možnost optimiranja cevnih mrež v katerih se pretaka vroča voda oz. raztopina aditivov. Razvit je matematični model in na njegovi osnovi napisan računalniški ... program za določanje optimalne drevesne pretočne poti optimalnih premerov cevne mreže. Raziskan je vpliv vodne raztopine kationskih površinsko aktivnih aditivov na zmanjšanje intenzivnosti turbolence, kar vodi do zmanjšanja odpora pri pretoku fluidov po ceveh in posledično do manjše izgube tlaka, manjše potrebne moči črpalk, znižanja črpalnih stroškov, povečanja masnega pretoka, zmanjšanja stroškov plina za ogrevanje vode, zmanjšanja toplotnih izgub ter možnost uporabe cevi z manjšimi premeri. Kot končni rezultat dela je izvedena ocena rezultatov optimiranja. Razvidno je, da uporaba aditivov zaradi zmanjšanja odpora pri pretoku fluida povzroči spremembo optimalne drevesne pretočne poti. Sprememba je posledica znižanja izgube tlaka v ceveh, kar omogoča 15,7% zmanjšanje naložbe v črpalko in 31,8% zmanjšanje črpalnih stroškov.Type of material - master's thesisPublication and manufacture - Maribor : [A.
