A Study of Pressure Distribution of A Slider Bearing Lubricated with Powell-Eyring Fluid


Abstract: A slider bearing consisting of connected surfaces with Powell-Eyring fluid as a lubricant is analyzed in the present study. A Powell-Eyring model has been used as a non-Newtonian lubricant in a slider bearing. The analysis is based on the perturbation technique. Under the assumptions of the order of magnitudes of the variables, it is seen that only viscous and non-Newtonian terms have effects, whereas inertia terms are negligible. Choosing non-Newtonian effects smaller than viscous effects, a perturbation solution is constructed. The pressure distribution in the bearing is calculated approximately.
