Abstract

The aim of this investigation is to compare the magnetic fluid flow models for the ferrofluid lubrication of porous rough curved circular squeeze films incorporating slip velocity, wherein various film shapes are considered. The random irregularity of the bearing faces is characterized by a stochastic random variable with non-zero skewness, mean and variance. The concerned Reynolds type relation is averaged under Christensen and Tonder’s stochastic modeling. Using Reynolds boundary conditions, this expression is solved for the pressure distribution. Then the load bearing is determined. Magnetic fluid lubrication tends to overcome roughness’ adverse effect as much as possible. This result remains superior in Shliomis (SH) model for almost all film shapes. The novelty of this examination reveals that if designed properly Shliomis model based ferrofluid lubrication may be adopted from industry point of view even for some film shapes Neuringer-Rosensweig (NR)’s model can be a suitable option.
