Abstract
Adiabatic solutions are presented for a finite width, hydrodynamic, misaligned journal bearing with non-Newtonian lubricants, obeying the power law model. The film viscosity is taken to be an exponential function of temperature. The performance characteristics of a misaligned journal bearing with slenderness ratio of unity are obtained for various values of non-Newtonian power law index n in the range 0.4 to 1.2, eccentricity ratio ϵ in the range 0.2 to 0.8, and misalignment angles of 0.0001 and 0.0002 rad. The adiabatic solutions show that the load-carrying capacity is greatly reduced when compared with that given by the isothermal solutions. In addition, thermal effects are found to be more pronounced for higher values of flow behaviour index n, higher eccentricity ratios and larger misalignment angles.
