Abstract
In this second report, the effects of journal surface shear stress on the stability of rigid rotor supported by hydrodynamic journal bearings operated in the turbulent flow regime are examined theoretically for a wide range of bearing length-to-diameter ratios. Based on the finite width turbulent lubrication theory considering the fluid shear stress acting on the journal surface, the numerical solutions for the whirl onset velocities and journal center trajectories are obtained. It is clarified from the numerical results that the rate of decrease of whirl onset velocities due to the effects of journal surface shear stress under the constant Sommerfeld number decreases with an increase of bearing length-to-diameter ratio.
