RISComments on a Newly Identified Destabilizing Rotordynamic Mechanism Arising in Vertical Hydraulic Turbines and the Back Shrouds of Centrifugal Impellers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In three 2010 papers, Tsujimoto et al. (2010, “Moment Whirl Due to Leakage Flow in the Back Shroud Clearance of a Rotor,†Int. J. Fluid Mach. Syst., 3(3), pp. 235–244), Song et al. (2010, “Rotordynamic Instability ...
Vibration Modeling and Experimental Results of Two Phase Twin Screw Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In turbomachines, the transfer of energy between the rotor and the fluid does not—in theory—result in lateral forces on the rotor. In positive displacement machines, on the other hand, the transfer of energy between ...
Rotordynamics of a Two Phase Flow Twin Screw Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Twin screw pumps are positive displacement machines. Two meshing screws connected by timing gears push the fluid trapped in the screw cavities axially from suction to discharge. Available steady state hydraulic models ...
