Fluid inertia effects in a non-Newtonian squeeze film between two plane annuli

An analysis is presented for the laminar squeezing flow of an incompressible power-law fluid between parallel plane annuli using the modified lubrication theory and energy integral method. The local and the convective inertia of the flow are considered in the investigation. Analytical expressions for the load capacity of the squeeze film are obtained by both methods and are compared with those based on the assumption of inertialess flow. It is obsvered that the inertia correction for the load capacity is more significant for pseudo-plastic fluids, n < 1. For a Newtonian fluid, n = 1, expressions are obtained by using both methods and are compared with the a vailable results.
