Abstract

The objective of this paper is to predict the performance of a rotor bearing system, lubricated with couple stress fluid accounting the cross effect of velocities. Modified Reynolds equation and the Stokes constitutive equation have been obtained. Narrow bearing approximations have been used to obtain the solutions in the closed form. The effects of couple stress, frame rotation and the viscosity-density effects have been numerically obtained. The obtained results are consistent with the physical situation of the problem.
