The possibility of an incomplete lubricating film due to directed lubrication in hydrodynamic thrust bearings is considered. The free boundaries of the wetted area on a flat sector-shaped pad are determined by a simultaneous iterative solution of the Reynolds equation and a flow equation. Bearing load carrying capacity and power loss are calculated for a variety of inlet geometries, and a comparison is made with a complete fluid film bearing. It is found that bearing performance can be very much affected by the radial location of lubricant supply to the pads.
