Modeling and Experimental Validation of a Laval Rotor on Plain Journal- and Turbocharger Floating Ring Bearings - The Behavior of High Speed Rotors on Fluid Film Bearings

The first part of this thesis elaborates on two numerical models of different levels of comprehensiveness of a Laval rotor on plain journal bearings. These models are compared to an experiment, capable of rotating at 60 krpm, also devised in this research. Reasonable correlation in terms of whirl and whip behavior has been found. In the second...
