Three research groups are active in the field of Rotordynamic Testing and Analysis Codes at the Turbomachinery Laboratory. While some research and experiments overlap, each group has a distinct specialty as outlined below.
Performance and Reliability Group
DR. ADOLFO DELGADO
The R&P Group focuses on conducting fundamental and applied research to advance the state of the art of rotating equipment. The Group’s research projects span a wide variety of topics tailored to address different technical needs. From multi-year research development of new concepts to fast-paced short-term projects, we provide technical contributions to advance low TRL concepts and more immediate and practical solutions to our sponsors.
Vibration Controls and Electoromechanical Lab
Rotordynamics, Magnetic Bearings, Active Vibration and Noise Control, Fluid Film Bearings, Vibrations, Finite and Boundary Elements, Seal and Impeller Leakage Flow, Piping Systems, Machine Design, Flywheels, Machinery Couplings, Expert Systems, Microgravity Vibration Isolation, Electromechanical Systems
Tribology Group / Rotordynamics Lab
In the field of Tribology (friction, lubrication and wear) 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.
In the Rotordynamics field, research deals with the measurement and prediction of the dynamic lateral vibration characteristics of turbomachinery, encompassing both the traditional aspects of rotordynamics analysis and investigations into the fluid film-structure interaction forces that influence rotordynamics, with a major emphasis in fluid film dampers and gas bearings.
