RISOn-Site Identification of Dynamic Annular Seal Forces in Turbo Machinery Using Active Magnetic Bearings: An Experimental Investigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Significant dynamic forces can be generated by annular seals in rotordynamics and can under certain conditions destabilize the system leading to a machine failure. Mathematical modeling of dynamic seal forces are still ...
Design of Active Magnetic Bearing Controllers for Rotors Subjected to Gas Seal Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Proper design of feedback controllers is crucial for ensuring high performance of active magnetic bearing (AMB) supported rotor dynamic systems. Annular seals in those systems can contribute significant forces, which, in ...
Design and Calibration of a Full Scale Active Magnetic Bearing Based Test Facility for Investigating Rotordynamic Properties of Turbomachinery Seals in Multiphase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The recent move toward subsea oil and gas production brings about a requirement to locate process equipment in deepwater installations. Furthermore, there is a drive toward omitting well stream separation functionality, ...
