Numerical modelling of TEHL in bearings and gears

Advanced Lubrication - Nicolas Delaissé

A Thermo-Elasto-Hydrodynamic Lubricated (TEHL) contact is characterized by very thin lubrication films and locally extreme pressures, which results in a significant local elastic deformation of the solid surfaces. To gain clear physical understanding of this particular contact, it is necessary to evaluate fluid and structure phenomena together. The project aims at gaining fundamental understanding in the complex physics of TEHL in bearings and gears, with respect to the contact dynamics under variable operating conditions, using Fluid-Structure Interaction (FSI) modelling.
