CHARACTERISTICS OF MAGNETIC FLUID LUBRICATION ON THE PERFORMANCE OF A TRANSVERSELY ROUGH HYDRODYNAMIC SHORT JOURNAL BEARING

In this paper, a theoretical study of surface roughness on the hydrodynamic short journal bearing under the presence of a magneticfluid lubricant is presented. The magnetic fluid flow model of Neuringer Rosenwicg has been used here. The stochastic modeling of Christensen and Tonder has been employed to estimate the effect of transverse surface roughness. The modified Reynolds equation accounting for the surface roughness and magneticfluid lubricant is mathematically derived. The associated Reynolds’ type equation is solved with suitable boundary conditions to obtain the fluid film pressure distribution leading to the calculation of load carrying capacity. The results presented in graphical forms suggest that the combined effect of the magnetic fluid lubricant and negatively skewed roughness increases the load carrying capacity significantly. It is seen that the bearing can support a load even when there is no flow of lubricant. Cite this Article: Mehul P. Patel, Dr. H. C. Patel and Dr. G. M.
