On the thermal effects in hydrodynamic journal bearings

This paper presents recent works on temperature effects in hydrodynamic journal bearings. This is an over-view of several specific thermal problems encountered particularly in fixed geometry and tilting-pad journal bearings. The temperature-viscosity variation, the heat transfer, the change in bearing clearance, the thermal and mechanical deformations, the flow regime, the transient regime, the risk of seizure, the dynamic loading as well as the misalignment are successively discussed.
