Performance of asymmetric slot-entry hydrostatic and hybrid journal bearings lubricated under micropolar lubricant has been presented numerically. For chosen values of microploar parameters, the effects of micropolar lubricant on both the bearings have been simulated. FEM has been applied for the solution of Reynolds equation for micropolar lubricated asymmetric slot-entry bearings. Micropolar lubrication provides the larger minimum fluid film thickness for hydrostatic bearing than hybrid bearing. It has also been found that values of the coefficient of fluid film stiffness and damping are more for micropolar fluid lubricated hybrid journal bearing than hydrostatic bearing. The presented results of asymmetric slot-entry hydrostatic and hybrid journal bearings under micropolar lubrication are expected to provide the useful information to the bearing designer.
