On the basis of the Stokes microcontinuum theory and the Christensen stochastic model, a theoretical study of squeeze film performance for isotropic rough rectangular plates with couple stress fluids as lubricants is presented. A stochastic non-Newtonian Reynolds-type equation is derived and solved analytically for the mean film presure distribution. Squeeze film characteristics are then evaluated. According to the results, bearing surfaces with isotropic roughness pattern result in poor bearing characteristics as compared to the smooth-surface case. However. the isotropic rough plates with a non-Newtonian couple stress fluid provide a significant increase in the mean load-carrying capacity, and compensate the response time by more than the reduction caused by surface roughness.
