In this paper, we investigated theoretically and experimentally the inertia effect generated within the capillary restricted part in the case of a turbulent flow. From comparison with the experiment, it is concluded that the influence on the dynamic characteristics should be considerable, and that the presented analysis yields good predictions of both the bearing stiffness and the damping coefficient in a wide range of designing conditions.
