Abstract
The purpose of current study is to discuss the performance of a ferrofluid squeeze-film (SF) among a sphere and a POR (POR) flat plate when surface roughness (SR) and slip velocity (SV) are coupled. The well-known Neuringer-Rosensweig’s (N-R) theory has been used for the magnetic fluid flow (MFF). The surface irregularity effect was estimated using “Christensen and Tonder's stochastic averaging method”. Further, the slip conditions of Beavers and Joseph has been taken into account for the impact of SV. Evaluating the accompanying “stochastically averaged Reynolds type equation” yields the pressure distribution. The load-carrying capability (LCC) is then determined. The graphs show that, while ferrofluid lubrication increases load-bearing capacity (LBC), it may not be enough to counteract the joined negative effects of POR, standard deviation (SD), and slip. However, the situation eases when the slip parameter is at its smallest and variance (-ve) occurs in the case of adversely skewed roughness. Lastly, a comparison of the present findings with a previously published work indicates that a transverse SR uplifts the LBC by at least 68 percentage.
