| Abstract | Multilayered porous media can be found widely in both natural and engineered systems. This type of heterogeneous porous structure can have a substantial influence on the effective flow and transport processes. This work aims to develop a hybrid analytical-numerical solution that elucidates the relationship between the scalar dynamics and media properties in a coupled system comprising a two-dimensional free-flow layer and a heterogeneous porous medium, operating under fully developed laminar flow conditions. In our study, we employ perturbation and homogenization methods to derive a set of one-dimensional upscaled equations for transport of a passive scalar. Subsequently, we develop an integral transform-based semianalytical solution that allows to relate the properties of the porous system to scalar mixing and spreading. To validate the newly developed solution for the upscaled system, we compare it with the numerical results for the two-dimensional scalar transport. The semianalytical solution is used to investigate the influence of the multilayered system on macroscopic transport by analyzing the scalar cloud's breakthrough curve, dispersion coefficient, and mixing. Our findings indicate that the semianalytical solution can be utilized to optimize and control dispersion of the scalar cloud. Our computational results show the potential of the solution to determine the arrangement of porous media properties to achieve a desired mixing objective. |
