The purpose of this paper is to derive lubrication equations suitable for constant-property fluids exhibiting inelastic non-Newtonian characteristics. The analysis results in a slightly modified form of Reynolds equation. Fluid characteristics show up in this equation through an equivalent power-law. Data are presented for journal bearing performance over a range of L/D’s and rheological exponents.
