The present work presents a bulk flow based numerical analysis of squeeze film dampers (SFD) provided with circumferential grooves, feeding orifices and piston ring sealing devices. This means that the bulk flow model for inertia dominated flow regimes (high Re) was adapted for taking into account thin film discontinuities, mass sources located in the thin film zone (for modelling feeding orifices) or on the boundaries (piston ring seals with open slots). In the present work the rotor is whirling on a centered whirl and the bulk flow equation are solved by following a time step integration.
