Analysis of Micropolar and Power Law Fluid�Lubricated Slider and Journal Bearing with Partial Slip�Partial Slip Texture Configuration

An analysis of micropolar and power law fluid�lubricated partial slip�partial slip texture slider and journal bearings is presented. The nondimensional pressure and shear stress expressions for a partial slip texture configuration are analyzed using narrow groove theory. The parameters used in the analysis are nondimensional partial slip length, nondimensional partial slip�partial slip texture length, nondimensional depth of recess, ratio of land with slip to recess, nondimensional slip coefficient, coupling number; ratio of characteristic length to film gap, and power law index. A partial slip configuration with a higher slip coefficient yields an improvement in load capacity and reduction in coefficient of friction compared to a partial slip texture configuration for micropolar and power law shear thinning (pseudoplastic) fluid-lubricated slider and journal bearings. © 2016 Society of Tribologists and Lubrication Engineers.
