The results indicate that the bearing performance gets adversely affected by the surface roughness, bearing deformation combination, even if, a magnetic fluid has been considered as the lubricant. However, the negatively skewed roughness introduces a better performance for a good range of deformation by suitably choosing the curvature parameters. It is appealing to note that, although there are several factors bringing down the load carrying capacity, still the bearing can support a good amount of load even when there is no flow unlike, the case of conventional lubricants. In addition, this article also emphasizes the role of rotation for improving the bearing performance. http://pubs.sciepub.com/marine/3/1/1/marine-3-1-1.pdf circular plates magnetic fluid roughness deformation rotational inertia load carrying capacity
