The physics of porous media is, when taking a broad view, the physics of multinary mixtures of immiscible solid and fluid constituents. Its relevance to society echoes in numerous engineering disciplines such as chemical engineering, soil mechanics, petroleum engineering, groundwater engineering, geothermics, fuel cell technology… It is also at the core of many scientific disciplines ranging from hydrogeology to pulmonology. Perhaps one may affix a starting point for the study of porous media as the year 1794 when Reinhard Woltman introduced the concept of volume fractions when trying to understand mud. In 1856, Henry Darcy published his findings on the flow of water through sand packed columns and the first constitutive relation was born. Wyckoff and Botset proposed in 1936 a generalization of the Darcy approach to deal with several immiscible fluids flowing simultaneously in a rigid matrix. This effective medium theory assigns to each fluid a relative permeability, i.e. a constitutive law for each fluid species. It remains to this day the standard framework for handling the motion of two or more immiscible fluids in a rigid porous matrix even though there have been many attempts at moving beyond it. When the solid constituent is not rigid, forces in the fluids and the solid phase influence each other. von Terzaghi realized the importance of capillary forces in such systems in the thirties. An effective medium theory of poroelasticity was subsequently developend by Biot in the mid fifties. Biot theory remains to date state of the art for handling matrix-fluid interactions when the deformations of the solid phase remain small. For large deformations, e.g. when the solid phase is unconsolidated, no effective medium theory exists.

This monograph is the first book exclusively devoted to Electrohydrodynamics in Dusty and Dirty Plasmas with extended Electrodynamics and Gravito-Electrodynamics with Electric Mirrors. The book incorporates novel concepts of Electro Cusp-Reconnection and Generalized Critical Ionization Velocities as well as modern concepts of Self-Organization and Chaos. Therefore, the book is special and quite different from the previous edition in the field of plasma physics in terms of scope, object, and approach. The scope of the present work is much broader and much more general with space and laboratory applications, including collisional neutral and partially ionized gases in electric and space-charge fields, thereby accompanying electrical charging, electrification, discharge, ionization and recombination. The book will serve as a text book, text-related or reference book for graduate students, post graduates, and scientists in geo-astro, space, and laboratory plasma physics, electromagnetics and fluid dynamics. In addition, it will be useful for researchers outside the plasma community who wish to obtain new physical insights, aspects, and points of view.

This book provides an overview of essential research on and developments in the electrohydrodynamic (EHD) direct-writing technique and its applications. Firstly, it presents mechano- and helix electrospinning methods to achieve direct writing of straight/serpentine micro/nano fibers in high resolution. Secondly, it examines functional inks and multi nozzle arrays for EHD printing, which are used to efficientlyform patterns and devices. Thirdly, the book discusses the various control methods adopted in the context of EHD to improve the controllability of the electrospun fibers. Lastly, it addresses the equipment used in EHD printing and its applications, while also outlining challenges for the field’s future development. Combining academic and industrial viewpoints, the book provides in-depth information for experienced researchers, as well as a valuable guide for those just entering the field.
