Abstract
This article presents a numerical analysis on anomalous transport behavior in a heterogeneous fractured porous reservoir using streamlines. The authors developed a streamline simulator with a direct quadrilateral mesh generator to investigate the correlated effects of hydrological properties. Quadrilateral grids were made by constructing boundary loops automatically. The mesh generator showed reliable shapes and did not need to construct another control volume for a conventional transport model. Solute was transported using a streamline approach on the irregular grids with various values of permeabilities between matrix and fracture. Breakthrough curve has a skewed characteristic similar at a real heterogeneous medium. The trajectories of streamline, the distribution of pressure, and the skewed breakthrough confirm the applicability of our model at both porous and fractured medium.
