Title : Senior Researcher - CNRS

Fields of expertise

  • Numerical computation
  • Experimentation
  • Surface Characterization
  • Lubrication
  • Rheology
  • Thermal Analysis

Activities :

Research activity :

- Rheological behavior of fully formulated lubricants (oils, greases, emulsions, additives): characterization and modeling

- Relationship between lubricants composition & structure and their rheological & tribological behavior

- Film thickness and traction prediction in elastohydrodynamic (EHD) contacts by numerical modeling including non Newtonian approaches

- Experimental simulation of actual highly loaded contacts, lubrication regime identification

- Development of in situ techniques to map physical and mechanical parameters within lubricated contacts

 

Applications :

- ball and roller bearings
- mechanisms boarded on satellites
- metal forming
- internal combustion engines
- watch micro mechanisms

Dissipation within EHD contacts: sliding influence
