Mortar upscaling for multiphase flow in porous media

  title={Mortar upscaling for multiphase flow in porous media},
  author={Małgorzata Peszyńska and Mary F. Wheeler and Ivan Yotov},
In mortar space upscaling methods, a reservoir is decomposed into a series of subdomains (blocks) in which independently constructed numerical grids and possibly different physical models and discretization techniques can be employed in each block. Physically meaningful matching conditions are imposed on block interfaces in a numerically stable and accurate way using mortar finite element spaces. Coarse mortar grids and fine subdomain grids provide two-scale approximations. In the resulting… CONTINUE READING
