This open access book presents a thorough look at tortuosity and microstructure effects in
porous materials. The book delivers a comprehensive review of the subject summarizing all key
results in the field with respect to the underlying theories empirical data available in the
literature modern methodologies and calculation approaches and quantitative relationships
between microscopic and macroscopic properties. It thoroughly discusses up to 20 different
types of tortuosity and introduces a new classification scheme and nomenclature based on direct
geometric tortuosities indirect physics-based tortuosities and mixed tortuosities (geometric
and physics-based). The book also covers recent progress in 3D imaging and image modeling for
studying novel aspects of tortuosity and associated transport properties in materials while
providing a comprehensive list of available software packages for practitioners in the
community. This book is a must-read for researchers and students in materials science and
engineering interested in a deeper understanding of microstructure-property relationships in
porous materials. For energy materials in particular such as lithium-ion batteries tortuosity
is a key microstructural parameter that can greatly impact long-term material performance. Thus
the information laid out in this book will also greatly benefit researchers interested in
computational modeling and design of next-generation materials especially those for
sustainability and energy applications.
