Sažetak
Uložen je trud da se ispitaju i analiziraju performanse Jenkins-ovog modela zasnovanog na ferofluidnom filmu u zakrivljenim hrpavim kružnim pločama uzimajući u obzir uticaj brzine klizanja. Korišćen je Beavers-ov i Joseph-ov model klizanja kao i Christensen-ovo i Tonder-ovo stohastičko modeliranje. Uz pomoć odgovarajućih graničnih uslova, povezana Reynold-ova jednačina je rešena kako bi se dobio izraz za distribuciju pritiska, što je otvorilo put ka izračunavanju kapaciteta nosivosti. Grafički prikazi jasno pokazuju da iako kapacitet nosivosti znatno raste sa povećanjem magnetizacije, magnetizacija ima ograničene mogućnosti za ublažavanje negativnih efekata brzine klizanja i standardne devijacije. Međutim poželjno je da parametar klizanja bude na minimumu iako su odabrani odgovarajući parametri krivine. Na kraju, Jenkins-ov model ide dalje od Neuringer-Rosensweig modela u smanjivanju negativnih efekata hrapavosti.
