The homogenization method of roughness analysis in turbulent lubrication
The hydrodynamic lubrication theory founded by Osborne Reynolds in 1886 is based on
several assumptions, including that the contact surfaces are perfectly smooth, and the
lubricant flow regime is laminar. However, in certain special cases these hypotheses may
not be valid, and it is seen that surface roughness and turbulence affect bearing
performance. The approach adopted in the present work is based on the application of the
homogenization method to the turbulent Reynolds equation. In homogenization, multiscale …
