Tortuosity and Microstructure Effects in Porous Media: Classical Theories, Empirical Data, and Modern Methods

Tortuosity and Microstructure Effects in Porous Media: Classical Theories, Empirical Data, and Modern Methods

Lorenz Holzer, Philip Marmet, Mathias Fingerle, Andreas Wiegmann, Matthias Neumann, Volker Schmidt

Empirical data shows that the tortuosity-value of a certain microstructure is more strongly dependent on the type of tortuosity than on the microstructure itself. To clarify the discussion on this topic, a new classification scheme and a systematic tortuosity-nomenclature are proposed. Three main classes of tortuosity are distinguished and thoroughly discussed: direct geometric, indirect physics-based and mixed tortuosities.

Book contents:

• Review of theories and a new classification of tortuosity types
• Tortuosity-porosity relationships: review of empirical data from literature
• Image-based methodologies, workflows, and calculation approaches for tortuosity
• Towards a quantitative understanding of microstructure-property relationships
