Description
Tribology. Instructor: Dr. Harish Hirani, Department of Mechanical Engineering, IIT Delhi.
Tribology deals with design of fluid containment systems like seals and gasket, lubrication of surfaces in relative motion to achieve reduced friction and wear. The structure of the bearing and the nature of fluid flow determine the loads that can be supported. Modeling systems as hydrostatic, squeeze film and elasto-hydrodynamic lubrication will be studied as infinite and later finite structures. Gas (air) lubricated and rolling contact type motions with deformation at contact will be studied as special systems. (from nptel.ac.in)
