Abstract

The analysis of micropolar and power-law fluid lubricated journal bearing with partial texture is presented. The pressure and shear stress expressions (nondimensional) for micropolar and power-law fluids are derived based on narrow groove theory (NGT) using Reynolds boundary conditions. The nondimensional partial texture, micropolar and power-law fluid parameters considered in the analysis are: extent of texture region; land to cell extent ratio; depth of recess; coupling number, ratio of characteristic length to film gap and power-law index. The improvement in load capacity and reduction in coefficient of friction of partial texture journal bearings lubricated with micropolar and power-law fluids is evaluated.
