Abstract

Purpose

Our purpose was to theoretically analyse the effects of slip velocity and a magnetic fluid lubricant characterised by a material parameter on a parallel plate porous slider bearing. Various special cases were also discussed.

Design/methodology/approach

The analysis might be useful in designing better slider bearings useful in machines like gas turbines.

Findings

Computed values displayed in tabular form show that frictional force on the slider and the coefficient of friction decreased, the load capacity and the position of the centre of pressure unaltered when the slip parameter was increased. On the other hand, increase in the material parameter caused decrease in the frictional force and the coefficient of friction and, shift of the position of the centre of pressure towards the bearing inlet with no change in the load capacity of the bearing.

Originality/value

The parallel plate slider bearing cannot support a load with a conventional lubricant. However, it can support a load with a magnetic fluid lubricant with less frictional force on the slider.
