Description
  • We deal with a two-region porous media transport, which represent either solute transport in a medium with immobile pore zone (double or dual porosity) or solute transport with nonequilibrium sorption. The model consist of two coupled PDEs for mobile andNumerical solution is based on the finite volume method, with explicit upstream scheme for advection term and analytical solution of ODE representing the exchange between mobile and immobile zone. For suitable 1D problem, with exactly solved plain advection-dispersion problem, we show that after involving the effect of mobile-immobile exchange, the numerical solution is very close to the analytical solution. The results in example cases give a groundwork information for a use of the model for realistic problems.
