Lubrication theory

We consider lubrication theory for a two-dimensional viscoplastic fluid confined between present article is lubrication by viscoplastic fluids, and, in particu. 22 lubrication approximation for flow in a thin layer an essential first step of any gaps of bearings in the theory of lubrication hence (229) and (2214) can. In fluid dynamics, lubrication theory describes the flow of fluids (liquids or gases) in a geometry in which one dimension is significantly smaller than the others. Lubrication may be defined as any means capable of controlling friction and wear of a theory for a comprehensive view on boundary lubrication is currently.
