The lubrication of the mechanical components reduces friction, and increases the efficiency
and the reliability. However, the interaction of moving components with the lubricant leads to …

The air-lubricant interaction causes aeration which influences lubrication mechanisms in
rolling-element-bearings. The goal of this paper is to develop a Computational Fluid …

The acquisition of complex fluxes inside a Tapered Roller Bearing (TRB) via Particle Image
Velocimetry (PIV) is an experimental challenge. This can be successfully performed by …

Experimental studies on rolling-element bearing lubrication represent an ambitious
engineering challenge. In the present study, the design of a dedicated test rig to perform …

Efficiency improvement is the new challenge in all fields of design. In this scenario the
reduction of power losses is becoming more and more a main concern also in the design of …

To improve roller bearing efficiency, it is essential to identify the sources of power losses and
quantify them in the design stage, considering different influencing factors. For oil-lubricated …

To prevent severe friction between water-lubricated bearings (WLBs) and stern shafts under
harsh conditions, a method is introduced that uses a lubrication pump to supply a small …

This work concentrates on the journal bearing chamber of a gas turbine engine, to explain
the impacts of the rotational speed of the rotor on the velocity, pressure and temperature …

To reduce the lubrication failure of water-lubricated bearings under short-term harsh
conditions, preliminary experiments have shown that temporarily supplying a small amount …

Optimizing bearing performance is based on effective lubrication, especially in high-speed
machinery, where minimizing churning and drag losses is of significant importance. Over the …
