A mixed-TEHD analysis and experiment of journal bearings under severe operating conditions
TL;DR: In this paper, a steady-state mixed-TEHD (thermo-elasto-hydrodynamic) model for journal bearings is developed, which considers the fluid flow in the gap formed by rough surfaces, asperity contact, surface thermoelastic deformations, and a temperature-pressure-viscosity relationship for the lubricant, as well as an angular misalignment between the journal and the bearing.

A numerical method for the calculation of lubricant pressures in bearings with mixed lubrication
M.E. Weyler,Chih Wu +1 more
TL;DR: In this article, a model for mixed lubrication, assuming that the total normal load applied to the plane of the lubricated surfaces is carried partly by the hydrodynamic action of a lubrication film and partly by asperity contacts, was used to develop a numerical solution for pressure distribution.

Boundary conditions for the calculation of the dynamic characteristics of infinitely long journal bearings with turbulence and inertia effects
TL;DR: In this article, a discussion concerning the various pressure boundary conditions used in the calculation of the dynamic characteristics of infinitely long journal bearings under turbulent operating conditions including inertia effects is presented. But it is concluded that the pressure boundary condition plays an important role in determining the dynamic properties when turbulent and inertia effects are included.
