Imodeli elula yemathematika yokuhamba kwamanzi kuhlobo oluqhelekileyo lwe-sarped-surface exchanger ubushushu apho izikhewu phakathi kweencakuba kunye neendonga zesixhobo zimxinwa, ukuze inkcazo yethiyori ye-lubrication yokuhamba isebenze, ibonakaliswe.Ngokukodwa, ukuhamba okuzinzileyo kwe-isothermal ye-Newtonian fluid ejikeleze uluhlu lwamaxesha athile lwe-pivoted blades scraper kumjelo onodonga olulodwa olumileyo kunye nolunye udonga olushukumayo, xa kukho i-gradient yoxinzelelo olusetyenzisiweyo kwicala elixhomekeke kwintshukumo yodonga, luhlalutyo.I-flow in three-dimensional, kodwa ibola ngokwemvelo ibe yi-dimensional-dimensional "transverse" flow flowing by the boundary motion kunye ne-"longitudinal" eqhutywa ngoxinzelelo.Iinkcukacha zokuqala zesakhiwo se-transverse flow flow, kwaye, ngokukodwa, izikhundla zokulingana kwee-blades zibalwa.Kuboniswa ukuba uqhagamshelwano olunqwenelekayo phakathi kweencakuba kunye nodonga oluhambayo luya kufumaneka, ngaphandle kokuba ii-blades zipiwe ngokwaneleyo kufuphi neziphelo zazo.Xa uqhagamshelwano olufunwayo luphunyeziwe, imodeli iqikelela ukuba amandla kunye neetorque kwiiblades zisinye, kwaye ngoko imodeli ijikelezwe ngokubanzi ukubandakanya iziphumo ezithathu ezongezelelweyo zomzimba, ezizezi zingekho iNewtonian power-law-law, slip kwimida eqinile, kunye ne-cavitation. kwimimandla yoxinzelelo oluphantsi kakhulu, nganye kuzo iboniswa ukusombulula ezi singularities.Okokugqibela kuxoxiwe ubume bomqukuqelo welongitudinal.
