Non-Newtonian Behavior in Lubrication

Source

According to the classical theory of lubrication, viscosity is assumed to be a constant, and the conditions leading to the formation of a liquid film capable of supporting a load in a bearing can be calculated by hydrodynamics. However, even in normal liquids, complications occur that may change the viscosity. For example, during the operation of a sleeve bearing, frictional heat is evolved which causes a decrease in viscosity. The viscosity changes its value both across the film and at the surface of the bearing.
