It is essential to enhance the fuel efficiency of all machines to mitigate emissions and reduce energy consumption. Automobiles and machinery rely on lubricants for optimum operation and efficient energy transfer. In all mechanical systems, lubrication plays a major role […]
Surprisingly, when two lubricated solids are heavily loaded against one another and when a motion is applied to the solids surfaces, these two solids may not be touching one another (see Figure 1, left)! This […]
Definition of Elastohydrodynamic Lubrication (EHL) Elastohydrodynamic Lubrication – or EHL – is a lubrication regime (a type of hydrodynamic lubrication (HL)) in which significant elastic deformation of the surfaces takes place and it considerably alters […]
Reynolds equation is a partial differential equation that describes the flow of a thin lubricant film between two surfaces. It is derived from the Navier-Stokes equations and is one of the fundamental equations of the […]
