چکیده

Abstract We consider the homogenization of a Poisson problem or Stokes system in randomly punctured domain with Dirichlet boundary conditions. assume that holes are spherical and have random centres radii. impose average distance between balls is size $$\varepsilon $$ ? their radius ^{\alpha }$$ ? , $$\alpha \in (1; 3)$$ ? ( 1 ? 3 ) . prove that, as periodic case (Allaire, G., Arch. Rational Mech. Anal. 113(113):261–298, 1991), solutions converge to solution Darcy’s law (or its scalar analogue Poisson). In same spirit (Giunti, A., Höfer, R., Ann. Inst. H. Poincare’- An. Nonl. 36(7):1829–1868, 2019; Giunti, Velàzquez, J.J.L., Comm. PDEs 43(9):1377–1412, 2018), we work under minimal conditions on integrability These ensure well-defined but do not rule out onset clusters holes.

The Periodic Unfolding Method in Perforated Domains

The periodic unfolding method was introduced in [4] by D. Cioranescu, A. Damlamian and G. Griso for the study of classical periodic homogenization. The main tools are the unfolding operator and a macro-micro decomposition of functions which allows to separate the macroscopic and microscopic scales. In this paper, we extend this method to the homogenization in domains with holes, introducing the...

Examination of Darcys law for flow in porous media with variable porosity.

Henry Darcy's experimental studies in 1856 of saturated water flowthrough a homogeneous porous medium contained in a vertical column have provided the basis for the quantitative description of fluid flow in a wide variety of both natural and engineered porous medium environmental systems. Extrapolation of Darcy's original observations and conclusions has led to several commonly applied equation...

Stress computations on perforated polygonal domains ∗

A high order accurate and fast algorithm is constructed for 2D stress problems on multiply connected finite domains. The algorithm is based on a Fredholm integral equation of the second kind with non-singular operators. The unknown quantity is the limit of an analytic function. On polygonal domains there is a trade-off between stability and rate of convergence. A moderate amount of precomputati...

Two-Scale Convergence of Stekloff Eigenvalue Problems in Perforated Domains

By means of the two-scale convergence method, we investigate the asymptotic behavior of eigenvalues and eigenfunctions of Stekloff eigenvalue problems in perforated domains. We prove a concise and precise homogenization result including convergence of gradients of eigenfunctions which improves the understanding of the asymptotic behavior of eigenfunctions. It is also justified that the natural ...
