Abstract: The effect on the stability of a dynamically loaded journal bearing of introducing a pressure step is examined by calculating numerically the whirl orbits described by the journal for a range ...

Abstract: Dynamically loaded rotor bearings are frequently observed to perform whirling motions, in which the center of the rotor describes some sort of closed orbit. In this paper we demonstrate, by ...

Abstract: Whirl orbits have been calculated for a cavitated rotor bearing in which the cavity is assumed to form at an oil inlet groove and occupy the region in which subambient pressure is predicted ...

Abstract: We examine the flow in the annular region between two infinitely long parallel circular cylinders when the axis of the inner cylinder travels in a circular whirl orbit about the axis of the ...
