N2 - According to the Stokes micro-continuum theory of couple stress fluids together with the consideration of viscosity variation with pressure, the combined effects of piezo-viscous dependency, and non-Newtonian couple stresses in wide parallel rectangular-plate squeeze-film characteristics have been presented. An approximate analytical solution is obtained using a small perturbation method. Comparing with the iso-viscous and Newtonian case, the squeeze film performance is apparently improved. In addition, the improved characteristics are further emphasized for the squeeze film plates operating with a larger viscositypressure parameter, a non-Newtonian couple stress parameter and a lower film thickness.
