Tortuosity-porosity trends for in-line array of uniform shapes (circle or square). (a) Hydraulic tortuosity is a very weak function of porosity. (b) Diffusive tortuosity for in-line array of squares follows the analytical solution () from [48] closely, and both in-line array of squares and in-line array of circles match closely results by F.
