SAŽETAK:

Nestacionarno strujanje fluida i pojava hidrauličnog udara u svojim specifičnostima uključuju uslove okruženja u kojem se odvija strujanje fluida. Raznolikost materijala za izgradnju cevovoda (čelik, polietilen ili drugi materijal) definiše uslove za razvoj hidrauličnog udara. Predmet istraživanja u ovom radu su paralelno vezani cevovodi izrađeni od različitih materijala i međusobni uticaj u uslovima nestacionarnog  strujanja fluida. Izvršeno je numeričko istraživanje na dugim (pravim) cevovodima. Korišćen je softverski paket AFT-Impulse koji je već testiran uporednim eksperimentalno izmerenim vrednostima. Model za analizu razmatra paralelno vezane cevovode od čelika i polietilena. Rezultati simulacionih uslova dati su kroz uporedne dijagrame, gde se interaktivni uticaj jasno i nedvosmisleno otkriva. Uslovi eksploatacije i interaktivni uticaj dati su u komentaru i zaključku ovog rada.
