Abstract: This paper considers the transient analysis of rub problems in high-speed rotating equipment that involve interactions between the rotor, blades, and casing. Special emphasis is given to ascertaining ...

Abstract: Rub interactions between a rotor assembly and its corresponding casing structure has long been one of the major causes for machine failure. Fracture/fatigue failures of turbine impeller blade ...

Abstract: The study of the dynamics of turbomachinery during seismic events has been of continuous interest to both researchers and designers of large rotating equipment. Failure in such equipment, ...

Abstract: This paper describes a numerical procedure for analyzing the dynamics of transient and steady state vibrations in a wavy thrust bearing. The major effects of the wavy geometry and the operating ...

Abstract: The flow in an open lid, shear flow driven cavity with a jet penetrating at its bottom is described by a mathematical model that uses the Navier-Stokes equations written in terms of the ...

Abstract: More often than not, the rolling element bearings in rotating machinery are the mechanical components that are first prone to premature failure. Early warning of an impending bearing failure ...

Abstract: Hydrodynamic/hydrostatic journal bearings have been widely used in various types of high speed rotating machinery. For space applications, the issue of using cryogenic fluids as working lubricants ...

Abstract: Part 1 of this paper presented a numerical model that coupled the variable property Reynolds equation with a rotor dynamics model for the calculation of the nonlinear characteristics of a plain ...
