Magnetic Fluid Lubrication of an Infinitely Long Slider Bearing with Rough Surfaces

This article deals with the performance characteristics of an infinite slider bearing with rough surfaces in the presence of a magnetic fluid as the lubricant. The magnetic fluid flow model of Neuringer Rosenwicg has been used here. The stochastic model of Christensen and Tonder has been adopted to evaluate the effect of surface roughness. The related stochastically averaged Reynolds equation is solved to obtain the pressure distribution leading to the calculation of load carrying capacity. The results presented in graphical forms suggest that the adverse effect of transverse roughness can be minimized by choosing suitable magnetic strength. It is observed that the negativity-skewed roughness plays an important role in improving the bearing performance.
