Résumé : 

A number of studies have been carried out on the hydrodynamic lubrication of journal bearings. This articleseeks to summarize this work, presenting it in the form of a flow chart. The treatment of rupture andreformation of the film fluid in the contact region, for a steady loaded circular journal bearing, areaccomplished using the Reynolds and the Jakobsson–Floberg and Olsson (JFO) boundary conditions.A flow chart taking into account the resolution of some of the hydrodynamic lubrication problems is elaborated.A computer code is carried out for solving the Reynolds equation and for calculating the most importantparameters relating to a hydrodynamic contact. The obtained results for a finite-length bearing are comparedwith those obtained from the short-bearing hypothesis. In addition, a global thermal study is carried out in orderto evaluate the effect of temperature.
