Abstract:In this paper a fluid flow between two close located rough surfaces depending on their location and discontinuity in contact areas is investigated. The area between surfaces is considered as the porous layer with the variable permeability, depending on roughness and closure of surfaces. For obtaining closure-permeability function, the flow on the small region of surfaces (100 μm) is modeled, for which the surfaces roughness profile created by fractal function of Weierstrass-Mandelbrot. The 3D-domain for this c… Show more
