摘要
Convection-diffusion phenomena are analyzed by means of multiple scale expansion both in space and time when the macroscopic dimensions of the porous medium are much larger than the microscopic ones. Four different regimes are detailed and discussed depending upon the relative magnitude of the Peclet number. The results are compared with the prediction of the method of moments.
