Lubrication; Lubrication

The principle of interposing a material (liquid in this document) in the contact area to promote relative sliding between the two parts.

Continuous thin-film local lubrication mode

Special lubrication situation where a liquid lubricant (often oil) is present with a thickness greater than 0.1 µm. This thickness guarantees a sufficiently large number of molecules in the film thickness to guarantee fluid flow between the two walls.

Reynolds equation; Reynolds equation

General differential equation describing the behavior of a thin, continuous lubricant film obtained with a Newtonian fluid.

Newtonian fluid; Fluide newtonien

Fluid whose rheology follows Newton's law (shear stress is proportional...
