Idatha ehlobene yezindleko yezinhlobo zezitshalo zokuhlukaniswa kawoyela, zombili izinhlokodolobha kanye nokujwayelekile, zichaziwe, yize imithombo ishibilika. Ekugcineni, ezinye izinkomba zokuqhubeka nokuthuthuka zichaziwe, njengoba imboni yamafutha ibheka imishini efakwe embhedeni wasolwandle noma ngisho ezansi komthombo.

3.7.1 Ukusetshenziswa kobukhulu bezinhlayiyana
Amayunithi amaningi, njengehydrocyclonesFuthi abahlukanisi bamandla adonsela phansi, bakhiqiza ukwahlukana kosayizi nezinga elithile futhi idatha yosayizi wezinhlayiyana ingasetshenziselwa ukulinganisa okuningi (isibonelo 3.15).
Isibonelo 3.15 yisibonelo sokuncishiswa kwe-node imbali; Inikeza, ngokwesibonelo, inani lokuqala le-Genelized Squares Dissimization. Le ndlela yokuqhafaza ingasetshenziswa noma nini lapho kunedatha yengxenye eyeqile; Ngokusibonelo 3.9 kungenzeka ukuthi kusetshenziswe.
Isibonelo 3.15 Sebenzisa isivunguvungu njengendawo. I-node yesibili yisibonelo: Lesi yisibonelo sokufakwayo okungu-2 (okuphakelayo okusha kanye ne-ball mildischarge) nokukhipha okukodwa (okuphakelayo kwe-cyclone). Lokhu kunikeza enye ibhalansi yesisindo (isibonelo 3.16).
ESahlukweni 9 sibuyela kulesi sibonelo sokugaya sisebenzisa idatha elungisiwe ukunquma ijika lokuhlukanisa i-cyclone.
