TLDR
In this article, dry powder lubricants are used to overcome the degradation of dynamic oil bearings applied at elevated temperatures and extreme operating conditions, in order to overcome such conditions, dry powder is applied to the bearing.Abstract:
Hydrodynamic oil bearings applied at elevated temperatures and extreme operating conditions are subjected to the problem of oil degradation. In order to overcome such conditions, dry powder lubrica...read more

Kinetic theories for granular flow: inelastic particles in Couette flow and slightly inelastic particles in a general flowfield
TL;DR: In this paper, the authors studied the flow of an idealized granular material consisting of uniform smooth, but nelastic, spherical particles using statistical methods analogous to those used in the kinetic theory of gases.

Frictional–collisional constitutive relations for granular materials, with application to plane shearing
P. C. Johnson,R. Jackson +1 more
TL;DR: In this article, the authors propose constitutive relations and boundary conditions for plane shear of a cohesionless granular material between infinite horizontal plates, and show that not all the material between the plates participates in shearing and the solutions for the shearing material are coupled to a yield condition for the non-shearing material to give a complete solution of the problem.

Grain flow as a fluid-mechanical phenomenon
TL;DR: In this paper, the behavior of granular material in motion is studied from a continuum point of view, where individual grains are treated as the "molecules" of a granular "fluid" and the resulting equations are nonlinear and coupled.

A Review of Dry Particulate Lubrication: Powder and Granular Materials
TL;DR: In this article, a review of the literature related to dry particulate in sliding contacts is presented, and a classification system for the scientific works in the dry particulates tribology literature in terms of theory, experiments, and numerical simulations is proposed.
