ABSTRACT


A study on the performance of a ferrofluid based double layer porous rough sliderA study on the performance of a ferrofluid based double layer porous rough sliderbearing is presented. The stochastic model of Christensen and Tonder has been used to evaluatethe effect of surface roughness. The expressions for pressure distribution, load carrying capacity,friction coefficient, centre of pressure and temperature rise are obtained. The effect of double layerincreases the load carrying capacity and decreases the coefficient of friction. It is appealing to seethat the positive effect of double layered gets enhanced by the magnetic fluid lubrication. Thenegatively skewed roughness further augments this performance. However, for lower values ofmagnetization parameter the effect of temperature rise is not that significant. The centre of pressureshifts towards the outlet edge for lower to moderate values of magnetization.


Keywords: Slider bearing; roughness; magnetic fluid; double layered porous.
