In this paper, the effects of fluid inertia forces in annular parallel plates squeeze film bearings lubricated with pseudo-plastic fluids are investigated theoretically. The cubic equation obtained from the empirical flow curves for the pseudo-plastic fluids is used as the relation between shear stress and rate of shear. Approximating the inertia term in the momentum equation by the mean value averaged across the film thickness the film pressures are obtained, and the effects of inertia forces on the films pressures are discussed for various nonlinear factors.
