ABSTRACT

1- Introduction of the mathematical assumptions and tools 
     stationnarity, ergodicity, stochastic two-scale convergence, mixing, large deviations
2- Convergence results and macro models obtained  for :
      diffusion with random conductivity, two-phase flow in porous media with random  permeability,
  two-phase flow through randomly fractured porous media
3- Illustration of theoretical results by numerical simulations.
