NUMERICAL STUDY OF SQUEEZE FILM LUBRICATION BETWEEN POROUS AND ROUGH RECTANGULAR PLATES
RÉSUMÉ
In this paper, we study squeeze film lubrication characteristics between two rectangular plates, of which the lower plate is porous and the upper one has a roughness structure. The fluid in the film region is represented by a viscous, incompressible couple-stress fluid. The governing Reynolds equation, which incorporates the couple-stress fluid, roughness, and porosity of the material, is solved numerically using the multigrid method. Results show that the effects of couple-stress fluid and roughness are more pronounced compared to the Newtonian fluid and smooth case, respectively, whereas the effect of permeability is to decrease the pressure distribution and load capacity.
