“…A model is developed using this method that is then validated with another setup model by Shukla and Deheri [7]. The resulting compression can be used to understand how a ferrofluid bearing should be designed to meet the desired load under the influence of slip and porosity.…”

The focus of this paper is to propose an innovative mathematical model, which describes the influence of slip and transverse roughness on a hydromagnetic squeeze film in porous tilted pad bearing. The stochastic model of Christensen and Tonder is, applied to evaluate the effect of surface roughness. Beavers and Joseph slip model takes the care of slip effect. Applying these models which governing the fluid pressure; is solved for the calculation of load support. The closed form solution is, obtained for the pressure and load capacity as a function of various physical parameters. The effect of such parameters is, discussed through graphical representations. The computations indicate that slip has to be at minimum for any upgrading in the bearing design. Besides, the absence of flow fails to keep away the bearing from supporting good amount of load, which does not happen in the case of traditional lubricant.

“…The performance of the bearing system can be improved by suitably choosing the magnetization parameter and slip coefficient in the case of negatively skewed roughness. An endeavour was made by Shukla and Deheri 81 to discuss the performance of a transversely rough porous circular convex pad slider bearing in the presence of an FFs lubricant. With the aid of suitable boundary conditions, the associated stochastically averaged Reynolds' equation was solved to obtain the expression for pressure distribution.…”

Ferrofluids (FFs) are stable colloidal suspensions composed of single‐domain magnetic nanoparticles dispersed in a carrier liquid. And it is an intelligent material, exhibiting normal liquid behaviour coupled with superparamagnetic properties. Since the properties and the location of these fluids can easily be influenced by a magnetic field, FFs have recently attracted many scientific, industrial and commercial applications. Lubrication is one of the most important applications for FFs, and the advantage of FFs as lubricant, over the conventional ones, is that the former can be retained at the desired location with moderate magnetic fields. The main focus of this paper is to present a comprehensive review on FFs lubrication theories based on the three flow models of Neuringer–Rosensweig, Shliomis and Jenkins. Besides, a few experimental studies on FFs lubrication are discussed briefly. Copyright © 2015 John Wiley & Sons, Ltd.

“…It was established that the transverse surface roughness decreases their performances; they can be improved by suitably choosing the magnetization parameter and slip coefficient. Shukla and Deheri 34 investigate the performance of a transversely rough porous circular convex pad slider bearing using ferrofluid as lubricant. The associated stochastically averaged Reynolds equation was solved to obtain the expression for pressure distribution.…”

The present study investigates hydrodynamic lubrication by ferrofluids of finite journal bearings using the Jenkins model. A magnetic field created by displaced finite wire is used. A numerical solution for the modified Reynolds equation using the finite difference method is obtained. Static characteristics of finite journal bearings are analyzed using 2 control parameters: magnetic force coefficient and Jenkins viscosity. The obtained results are compared to those from Neurenger‐Rosensweig model. It is shown that pressure, load capacity, attitude angle, and side leakage increase and friction factor decreases when increasing the value of each control parameter at low and medium eccentricity ratios. However, the Jenkins viscosity parameter decreases the load capacity and increases the friction factor at high eccentricity ratios.
