Sažetak
U ovom radu dat je pokušaj ispitivanja i analize efekta brizne klizanja na performanse prevlake sa magnetnom tečnošću kod koničnih ploča uz uzimanje u obzir uzdužnog obrasca hrapavosti. Klizni model Biversa i Džozefa (Beavers and Joseph) korišćen je kako bi se izračunao efekat brzine klizanja. Uzet je stohastički usrednjen model Kristensena i Tondera (Christensen and Tonder) kako bi se procenio efekat uzdužne hrapavosti. Stohastički usrednjene jednačine Rejnoldsovog tipa rešene su kako bi se dobila raspodela pritiska koja rezultira izračunavanjem kapaciteta nošenja tereta. Rezultati pokazuju da se kombinovani negativni efekat brzine klizanja i hrapavosti može prevazići u velikoj meri pozitivnim efektom magnetizacije i standardnom devijacijom u slučaju negativno iskošene hrapavosti. Ovaj efekat se dalje pojačava kada je varijacija (-ve) na mestu. Značajan aspekt našeg istraživanja jeste da uprkos negativnom efektu brzine klizanja, hrapavi sistem zadržava određenu količinu tereta, čak i u odsutnosti toka koji se retko viđa u slučaju tradicionalnih koničnih sistema sa lubrikantom.
