Shape Changing Lubricants

Shell Global Solutions UK is conducting research to optimize lubricants for the fuel economy. A problem exists in creating a balance between energy efficient lubricants that decrease friction, and the higher wear created by the thinner oil film in the lower friction lubricant. There are also many points of contact with extremely high pressure, which increases the viscosity of the lubricant, causing the metal surface to deform elastically thus promoting lubrication.

Shell uses COMSOL Multiphysics to solve the complex lubrication problems. COMSOL allows Shell to develop models without using the existing proprietary code, simplifying maintenance and modification of models.
