Abstract

The paper presents an analysis of variation of PDV on the squeeze film lubrication between a sphere and a rough porous plate by using fluids that contain lubricant additives. By using Christensen’s stochastic approach, Darcy’s formula, Stoke's theory, and Baru’s formula modified Reynolds equation is derived which is highly non-linear. The perturbation technique is used to make it linear and expressions for dimensionless pressure, squeezing time and dimensionless load are derived. The predictions are presented graphically
