Upscaling of convection-diffusion eqution. One-dimensional case

We consider a convection-difussion process in highly heterogeneous medium with a high Peclet number. The averaged equations of the process are obtained in the case of periodic medium and extended to the non-periodic media. We give special attention to the one-dimensional case where we present some numerical results.
