Before revision: For example: Ball bearings Air bearings Journal bearings Squeeze film dampers in aircraft gas turbines Human hip and knee joints Lubricated gear contacts Reynolds Equation Adaptations In 1978 Patir and Cheng introduced an average flow model which modifies the Reynolds equation to consider the effects of surface roughness on partially lubricated contacts.
