摘要
We study the asymptotic behaviour of an incompressible viscous flow in a narrow gap with a thickness of order 77 and a rough surface. The roughness is defined by a quasi-periodical function with period E. In both cases, when 77 is smaller or at the same order as E, we obtain different Reynolds equations for the pressure. We have also studied the convergence of the stresses on the rough boundary and we discuss the different cases.
