A strong fluid/structure coupling scheme for thin incompressible flow in the contact interface at the roughness scale

Abstract : We develop a strong coupling scheme for the mechanical contact and the interfacial thin fluid flow problems. The scheme is applied for simulations on the microscopic level by taking into account roughness of the surfaces with the objective to obtain relevant macroscopic constitutive equation for transmissivity in sealing applications. The problem of trapped fluid is studied in detail : the monolithic coupling scheme is developed for mechanical contact affected by the pressurized fluid trapped in the wavy interface. Results on the evolution of the real contact area, maximal frictional force and global coefficient of friction are presented.
