Tokovni pojavi v cevnem razdelilniku "trifurkatorju". I. del, (eksperiment)Predin, Andrej, 1961- ; Klasinc, Roman, 1948- ; Biluš, IgnacijoTudi v fluidni tehniki se pogosto uporabljajo razvejani cevni sistemi, kot je primer razdelilnika iz ene v tri cevi ali trifurkatorja, pri katerem pričakujemo enakomerno porazdelitev celotnega ... volumskega toka v tri enake dele, če so vse tri cevi enakih premerov in postavljene simetrično glede na glavno os. Kadar je trifurkator izveden tako, da poteka delitev iz kroglastega zaključka v tri po premeru manjše in med seboj enake cevovode pod kotom 120 stopinj glede na glavno srednjo cev, je bilo med laboratorijskimi raziskavami opaženo občutno spreminjanje volumskega toka v obeh krajnih cevovodih. Eksperimentane meritve so bile izvedene na tehniški univerzi v Gradcu, in sicer na Inštitutu za vodne znanosti in upravljanje z vodotoki na eksperimentalnem modelu trifurkatorja, izvedenega iz prozornih cevi, tako da sta bila mogoča opazovanje s hitro kamero in uporaba LDA metode za določanje hitrostnih profilov. Rezultati meritev so potrdili pričakovano domnevo, da porazdelitev volumskih tokov ni enakomerna, saj se je v konusu/krogli pred razdelitvijo v tri cevi ustvarjal nestacionarni, dinamično spremenljivi povratni vrtinec, ki zdaj v eni, nato v drugi skrajni veji blokiral oz. zmanjšal tokovni prerez in tako znižal volumski tok, saj so se pretočne izgube povečale.Source: Ventil : revija za fluidno tehniko in avtomatizacijo = journal for fluid power and automation. - ISSN 1318-7279 (9, 4, 2003, str. 204-209)Type of material - article, component partPublish date - 2003Language - slovenianCOBISS.SI-ID - 8480278
