This article makes an effort to present a comparative study on the performance of a Shliomis model-based ferrofluid (FF) lubrication of a porous squeeze film in curved annular plates taking slip velocity into account. The modified Darcy’s law has been adopted to find the impact of the doublelayered porosity, while the slip velocity effect has been calculated according to Beavers and Joseph’s slip conditions. The modified Reynolds equation for the double-layered bearing system is solved to compute a dimensionless pressure profile and load-bearing capacity (LBC). The graphical results of the study reveal that the LBC increases in the case of magnetization, volume concentration and upper plate’s curvature parameter while it decreases with other parameters for both the film thickness profile. A comparative study suggests that the exponential film thickness profile is more suitable to enhance LBC for the annular plates lubricated by ferrofluid, including the presence of a slip. The study shows that the slip model performed quite well and there is a potential for improving the performance efficiency. Besides, multiple methods have been presented to enhance the performance of the above mentioned bearing system by selecting various combinations of parameters governing the system.

“…As per the literature, a porous medium is a well-known phenomenon to improve bearing systems' effect. Many authors dealt with the performance of porous medium in various magnetic fluid lubricated bearing systems: Agrawal (1986) in inclined slider bearing, Bhat and Deheri (1991) for composite slider bearing, annular discs by Bhat and Deheri (1991), Bhat and Deheri (1993) for circular discs, Shah and Bhat (2000) in circular plates, annular plates by Shah et al (2002), Patel and Deheri (2014) in curved circular plates, Deheri et al (2016) convex pad slider bearing and Vasanth et al (2018) for the annular plate. It was examined that the load-bearing capacity was affected by the porous medium.…”

The ferrofluid flow model of the Shliomis and continuity equation for the film and porous interface with the theory of Darcy, the modified Reynolds equation for ferrofluid squeeze film between curved annular plates is discussed with the impact of the rotation of Ferro-particles and slip velocity at the boundary. Beavers and Joseph’s slip conditions are adopted to study the impact of slip velocity. The generalized non-dimensional pressure equation is derived and expression for dimensionless load-carrying capacity is obtained for the same. The graphical representation suggests that the bearing's performance enhances due to ferrofluid, considering the appropriate values of parameters for slip velocity and porosity.
