In this paper, a theoretical analysis of hydrodynamic couplestress squeeze film lubrication with various plane geometries viz; circular, annular, elliptic and rectangular are studied. The Stoke’s couplestress fluid model is used to characterize the rheological behaviour of the lubricant with polymer additives. The modified Reynolds equation for the squeeze film lubrication is derived on the basis of Stokes micro-continuum theory for couple stress fluids. Squeeze film characteristics for various geometries under consideration are derived. The effect of couple stresses, shape of plate and porosity on the squeeze film characteristics are analyzed and are illustrated graphically. It is observed that, for all the lubricant film shapes under consideration, the effect of couple stress fluid is to increase the load-carrying capacity and to lengthen the squeeze film time as compared to the corresponding Newtonian case.
