Noncontacting asperities work with hydrodynamic lubrication
or elastohydrodynamic lubrication depending on the level of elastic deformation.

In this case, there is fully hydrodynamic lubrication
and the piston rotates relative to the interior surface of the cylindrical bore with a frequency equal to the shaft rotation frequency.
Tribology and tribochemistry research in Leeds, for instance, covers a broad portfolio of analytical and experimental projects studying friction and wear phenomena occurring in all contact modes, from dry to the hydrodynamic lubrication
From the Stribeck curve presented in Fujimoto et al.'s article , it shows that fuel economy improvement can be achieved by lowering the friction coefficient in both boundary and hydrodynamic lubrication
conditions through the introduction of friction modifier and lower viscosity of engine oil[4,5,6].
To analyze the hydrodynamic lubrication
property of micro-grooved oil-lubricated parallel slider bearings, Shi and Ni  established a two-dimensional computational fluid dynamics simulation model.
According to the hydrodynamic lubrication
theory, the thin film assumption in hydrodynamic bearings is characterized by the small ratio of film thickness to the bearing's other physical dimensions; that is, c [much less than] R.

In the design of journal bearings, the Sommerfeld number, or the bearing characteristic number, is a dimensionless quantity used extensively in hydrodynamic lubrication
The water-lubricated bearing in seawater desalination pump not only simplifies the structure but also reduces the friction and energy consummation caused by the mechanical drive, which is due to the small friction factor of elastic hydrodynamic lubrication
, and especially avoids the contamination caused by the leakage.
