Dispersion in Heterogeneous Porous Media : One-Equation Non-equilibrium Model

  title={Dispersion in Heterogeneous Porous Media : One-Equation Non-equilibrium Model},
  author={Michel Quintard and Fabien Cherblanc and Stephen Whitaker},
Abstract. In this paper, the method of large-scale averaging is used to develop two different oneequation models describing dispersion in heterogeneous porous media. The first model represents the case of large-scale mass equilibrium, while the second represents the asymptotic behavior of a twoequation model obtained by large-scale averaging. It is shown that a one-equation, non-equilibrium model can be developed even when the intrinsic large-scale averaged concentrations for each region are… CONTINUE READING
