Mathematical Analysis of Effects of Surface Roughness on Steady Performance of Hydrostatic Thrust Bearings Lubricated with Rabinowitsch Type Fluids

Mathematical Analysis of Effects of Surface Roughness on Steady Performance of Hydrostatic Thrust Bearings Lubricated with Rabinowitsch Type Fluids

The objective of present theoretical analysis is to study the combined influence of surface roughness and lubricant inertia on the steady performance of stepped circular hydrostatic thrust bearings lubricated with non-Newtonian Rabinowitsch type fluids. To take the effects of surface roughness into...
