Imwe nzira yakapfava yemasvomhu yekuyerera kwemvura mumhando yakajairika yeyakavhurika-pamusoro-soro yekupisa kupisa umo mikaha pakati pemashizha nemadziro emidziyo yakamanikana, kuitira kuti tsananguro yerubrication-theory yekuyerera ishande, inoratidzwa.Kunyanya, kuyerera kwakadzikama isothermal kuyerera kweNewtonian fluid yakatenderedza nguva nenguva yepivoted scraper blades muchiteshi chine imwe yakamira uye imwe inofamba madziro, kana paine inoiswa yekumanikidza gradient munzira inotenderera kumadziro kufamba, ndiko kuongorora.Kuyerera kune-matatu-dimensional, asi kunoparara zvakasikwa kuva maviri-dimensional "transverse" kuyerera kunofambiswa nemuganhu wekufamba uye "longitudinal" inotyaira inotyaira inoyerera.Chekutanga ruzivo rwechimiro chekuyerera kwechinjika inotorwa, uye, kunyanya, nzvimbo dzakaenzana dzemablades dzinoverengerwa.Zvinotaridza kuti kubatanidzwa kunodiwa pakati pemablades nemadziro anofambisa kuchawanikwa, chero iwo mablades akapinzwa zvakakwana padyo nemigumo yawo.Kana iyo yaunoda kuonana yawanikwa, modhi inofanotaura kuti mauto uye torque pamashizha ari mumwechete, uye saka modhi yacho inogadzirwa kuti ibatanidze mamwe matatu emuviri maitiro, ayo asiri eNewtonian simba-mutemo maitiro, kutsvedza pamiganhu yakaoma, uye cavitation. mumatunhu ekudzvinyirirwa kwakaderera, imwe neimwe inoratidzwa kugadzirisa izvi singularities.Pakupedzisira chimiro chekuyerera kwelongitudinal chinokurukurwa.
