Zusammenfassung:In this paper, the effect of PDV on the couple stress squeeze film lubrication between rough porous circular plates is presented. Keeping the base of Christensen's stochastic theory, modified Reynolds equation is derived. Fluid film pressure, squeeze film time and load carrying capacity are solved using standard perturbation technique. The results are presented graphically for selected physical parameters and found that the squeeze effect is depleted in a porous bearing compared to its non-porous and increasing permeability has an adverse effect on the pressure, load carrying capacity and time of approach. Keywords: couple stress, porous, squeeze film, pressure dependent viscosity. AMS Subject Classification: 76D08, 76A05, 35K41, 49L25.
