Based upon the Stokes micro-continuum theory, the influence of the behaviour of journal bearings with couple stress fluids on the dynamics of rotor-systems have been studied by several Authors during the last decade. This paper is a part of a general approach aimed to the performances of the couple stress lubricants used to minimize the friction losses in steady operating conditions. Its purpose is to illustrate a method to formulate with closed-form solutions the steady/unsteady fluid film forces for the “infinitely long” and “finite” lubricated couple stress journal bearings, assuming the micro-continuum Stokes model. The model allows the advantage of minimising the computational time required for the analysis dynamic states of couple stress journal bearings without any significant loss of accuracy, while the analytical form of the solution involves a better readability of the parameter effects on the system unsteady behaviour.
