overview

Our research focuses on experimentally verified computational film flow models for the prediction of the static and dynamic force response of fluid film bearings; in particular hydrostatic bearings, tilting pad bearings, annular pressure seals, squeeze film dampers, floating ring bearings, gas damper bearings and seals, foil gas bearings and porous-carbon bearings.
