Abstract

A magneto-hydrodynamic wide composite slider bearing lubricated with couple-stress fluids is numerically analysed. A modified Reynolds equation has been derived to account for the transverse magnetic field in the couple-stress fluid lubrication of wide composite slider bearings. The closed form expressions are obtained for the non-dimensional fluid film pressure, load carrying capacity, frictional force and coefficient of friction. It is found that the fluid film pressure, load carrying capacity, frictional force and coefficient of friction increases as the strength of the magnetic field increases. The results are compared with non-magnetic case.

Keywords
