Abstract: The critical speeds for onset of Taylor vortices inflow between eccentric rotating cylinders are determined by means of torque measurements for various eccentricity ratios and clearance ratios ...

Abstract: An analytical method is described for predicting the operating temperature of thrust bearings of the size and speed typically found in large vertical machinery. The method involves evaluating ...

Abstract: This paper summarizes an analytic and experimental investigation of hydrostatic bearings for use in high-pressure cryogenic rocket engine turbopumps. A hydrostatic bearing analysis was developed ...

Abstract: An analysis for helical bearings operated in turbulent regime, with negligible inertia in an incompressible fluid film, was performed [10, 11]. The analysis is based on the linearised lubrication ...

Abstract: A turbulent energy model for determination of turbulent stresses is used to calculate velocity profiles in lubricant films. The results agree very well with the predictions of the previously ...

Abstract: A differential equation is obtained for the smoothed “overall” pressure distribution around a herringbone-grooved, gas-lubricated journal bearing operating with a variable film thickness. The equation ...

Abstract: Self-heating during operation causes a bearing to undergo thermal distortion. A method is presented to determine the consequent effects on the load capacity of a spiral-grooved air-lubricated ...

Abstract: A means of handling both fluid film turbulence and the effects of fluid convective inertia in bearing films has been developed. The analysis employs a number of simplifying assumptions but has ...
