Partial Surface Texturing in Hydrodynamic Lubrication: A CFD-Based Investigation

Facilitating the Study of the Texturing Effect on Hydrodynamic Lubrication

To facilitate fundamental study of the surface texturing effect on hydrodynamic lubrication, analytical and experimental tools are required. While there is an extensive amount of theoretical and analytical analyses in the literature, relevant experimental studies are much rarer. A detailed study requires techniques by which one can (a) produce micron-sized textures on a millimeter-scale area on...

An Investigation On Deformation-Based Surface Texturing

Surface textures have various applications, such as friction/wear reduction and light absorbing enhancement. Deformation-based surface texturing has the potential of economically creating micro-scale surface textures over a large surface area. A novel desktop surface texturing system is proposed for efficiently and economically fabricating microchannels on the surface of thin sheet material for...

On Turbulence in Hydrodynamic Lubrication

The contribution deals with a self-consistent description of time-mean turbulent lubricant flow, i.e. flow through a wedgeshaped gap confined by counter-sliding solid surfaces. The methods adopted are matched asymptotic expansions, where the slenderness or aspect ratio of the gap and the accordingly defined Reynolds number represent the perturbation parameters. As a remarkable finding, a load-b...
