Resumo: This study aims to analyze the performance of a transversely rough porous parallel slider bearing under the presence of a magnetic fluid lubricant flowing as par Shliomis model, taking velocity slip in to account. The associated stochastically averaged Reynolds equation is solved to get the pressure distribution thereby leading to the calculation of load carrying capacity. Further, the friction is computed. THe results show that magnetization not only increases the load carrying capacity but also increases the friction. But the slip parameter decreases the load carrying capacity as well as the friction. Besides, it is noticed that the standarddeviation and the positively skewed roughness decrease the friction. It becomes clear from this investigation that the magnetization can minimize the adverse effect of roughness up to some extent when relatively small values of the slip parameter are involved. A comparison of this investigation with the Neuringer-Rosensweig model indicates that the reduction of the adverse effect of roughness is comparatively more here. This article makes it clear that the bearing can support a load even where there is no flow.
