Ferrofluid based secant shaped slider bearing

An impermeable bearing with a secant shaped slider and a stationary stator was analysed mathematically by taking a ferrofluid lubricant whose flow followed the Jenkins flow behaviour. Expressions were obtained for various bearing characteristics. Computed values were displayed in graphical form. When the magnetization parameter was increased, load capacity of the bearing increased, coefficient of friction decreased, the position of the centre of pressure shifted towards the inlet of the bearing and the friction on the slider was unaltered. Contrary an increase in the material parameter caused decrease in load capacity, increase in friction and coefficient of friction and shift of the position of the centre of pressure towards the inlet
