16. Lubrication of conformal contacts with surface texturing
Sammanfattning : Conformal contacts like those found in journal or inclined slider bearings are widely encountered in various types of machines from small engines to large turbines. These contacts involve convergent gaps that are used to separate the surfaces in relative motion and generate pressure in the lubricant film. LÄS MER
17. Thermohydrodynamics of sliding contacts with textured surfaces
Sammanfattning : Hydrodynamic sliding contacts like those found in journal or thrust bearings are frequently encountered in various types of machinery from computers to large turbines. These contacts, involving a variation in film thickness, are used to generate pressure in the lubricant film and separate the surfaces in relative motion. LÄS MER
18. Lubrication of sliding bearings for hydropower applications
Sammanfattning : The term "sliding bearing" refers to types of bearing where two conformal surfaces (usually the stationary bearing and a moving shaft) slide relative to one another with load distributed directly across the interface. A suitable lubricant may be employed to reduce the friction between these two surfaces. LÄS MER
19. Investigations for enhanced tribological performance of a hydraulic motor
Sammanfattning : A radial piston hydraulic motor has several components that encounter sliding orrolling motion under lubricated conditions. When a hydrostatic, hydrodynamic orelastohydrodynamic oil film separates the interacting surfaces, the wear and frictionare low provided of course the hydraulic fluid is free from the presence ofcontaminants.

20. Numerical and experimental study of performance of a hydraulic motor
Sammanfattning : The aim of this study was to develop an understanding of the fluid properties that influence the efficiency of hydraulic systems in a steady-state, especially components in hydrostatic transmission systems under different running conditions. The aim has also been to investigate and model the sources of losses in hydraulic machines, in order to estimate the losses, taking fluid properties into account. LÄS MER
