The main purpose of the present study is to analyse the effect of sinusoidal magnetic field on a rough porous hyperbolic slider bearing system. The analysis is subjected to (i) Beavers and Joseph's slip model measuring the effect of slip velocity (ii) Christensen and Tonder's stochastic model representing the transverse surface roughness (iii) Sinusoidal magnetic field as suggested by Patel and Deheri. The novelty of the present study lies with the effect of sinusoidal magnetic field strength combined with the stochastic roughness of the bearing surface on pressure distribution and load-carrying capacity. The striking result reported in the present study is that the sinusoidal magnetic field enhances the loadbearing capacity by a factor * which amounts to 38.3% of increase in the load-carrying capacity. The magnetisation of the ferrofluid lubricant and slip parameter augment the load-bearing capacity within certain range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
