Imodeli yezibalo elula yokugeleza koketshezi ohlotsheni oluvamile lwesishintshi sokushisa esiklwetshiwe lapho izikhala phakathi kwama-blades nezindonga zedivayisi zincane, ukuze kuthulwe incazelo yetiyori yokuthambisa yokugeleza.Ngokukhethekile, ukugeleza kwe-isothermal okuzinzile koketshezi lwe-Newtonian okuzungeze uchungechunge lwezikhathi ezithile lwama-scraper ayi-pivoted esiteshini esinodonga olulodwa olumile nolodwa olunyakazayo, lapho kukhona i-gradient yengcindezi esetshenziswayo ekuqondeni okuncikene nokunyakaza kodonga, kuyahlaziywa.Ukugeleza kunohlangothi-ntathu, kodwa kubola ngokwemvelo kube ukugeleza “okuguquguqukayo” okuyizinhlangothi ezimbili okuqhutshwa ukunyakaza komngcele kanye nokugeleza okuqhutshwa yingcindezi “longitudinal”.Imininingwane yokuqala yesakhiwo sokugeleza okuphambene itholakala, futhi, ikakhulukazi, izindawo zokulinganisa zama-blades zibalwa.Kuboniswa ukuthi ukuxhumana okufunayo phakathi kwama-blade nodonga olunyakazayo kuzotholwa, inqobo nje uma izindwani zipiwuthiwe eduze ngokwanele neziphetho zazo.Uma kufinyelelwa ukuthintana okufunayo, imodeli ibikezela ukuthi amandla nama-torque kuma-blades amunye, ngakho-ke imodeli ijwayele ukuhlanganisa imiphumela emithathu eyengeziwe yomzimba, okungukuthi ukuziphatha komthetho okungewona we-Newtonian, ukushelela emingceleni eqinile, kanye ne-cavitation. ezifundeni ezinengcindezi ephansi kakhulu, ngayinye eboniswa ukuxazulula lezi zimo.Okokugcina kuxoxwa ngemvelo yokugeleza kwe-longitudinal.
