This paper aims to assess the behavior of hydrodynamic lubrication between surfaces with pores of different sizes. The profiles of the opposite surfaces are treated by lines with different number of pores that allow clarification of each of the surfaces influence on the lubricating film behavior.
A transient, spatially one-dimensional model of surfaces with surface-unequal pore numbers and sizes has been applied in the context of liquid lubrication. Special program for parametric study has been developed.
The calculations show that lubricating film between two surfaces with unequal pores provides better load support in comparison to the surfaces with equal pores. It is also shown that interaction between the pores of the opposite surfaces should be taken into consideration for defining better qualitative behavior of lubricating film.
The results of parametric calculations together with surface model can be used to design optimum lubrication quality of the rubbing surfaces.
The hydrodynamic behavior of a lubricating film between surfaces with different number of pore and their dimensions has been theoretically studied for the first time.
