This paper reviews the current knowledge on turbulence effects in tilting pad journal bearings. Turbulence is becoming increasingly important design of hydrodynamic bearings due to trend increase power density turbomachines and consequently operating speeds has a series bearing performance which may be beneficial or detrimental, depending conditions. The main models are recalled historical over...

The paper deals with the experimental characterization of different 280 mm diameter tilting pad journal bearings for turbomachines using a dedicated test rig. articles were 5-pad Direct Lube Rocker Pivot bearing, Flooded and 4-pad Ball Socket bearing. three tested in their specific design range operating conditions. Their static dynamic behavior was investigated as function parameters. In parti...
