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. Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. Lubrication Theory. It is well known that two solid bodies can slide over one another particularly easily when there is a thin layer of fluid sandwiched between . Theory of lubrication. Friction is the natural resistance to motion caused by surfaces that are in contact with each other. The purpose of lubrication is to reduce the harmful effects of friction by changing sliding friction to fluid friction. 16 Feb Definition of Hydrodynamic Lubrication (HL) Hydrodynamic lubrication theory is a theory used to reduce friction and/or wear of rubbing solids with the aid of liquid lubricant. For a vast majority of the surfaces encountered in nature and used in industry, the source of friction is the imperfections of the surfaces. 26 Aug  16 min  Uploaded by LTube Lubrication Theory  Part 1.
