Chapter 18 Elasto-Hydrodynamics of Quasicrystals and Its Applications 429 Tian You Fan and Zhi Yi Tang Preface “Water is the beginning of everything” (Tales of Mile to) “Air is the beginning of everything” (Anaxagoras of Mile to) Introduction Why is it important to study Hydrodynamics? The answer may be strictly technical, but it may also involve some kind of human feeling about our environment and our (eventual) limitations to deal with its fluidic constituents. As teachers, when talking to our students about the importance of quantifying fluids, we (authors) go to the blackboard and draw, in blue color, a small circumference in the center of the board, and add the obvious name 'Earth'. Some words are then said, in the sense that Hydrodynamics is important, because we are beings strictly adapted to live immersed in a fluidic environment (air), and because we are beings composed basically by simple fluidic solutions (water solutions), encapsulated in fine carbon membranes. Then, with a red chalk, we draw two crosses: one inside and the other outside the circumference, explaining: “our environment is very limited. We can only survive in the space covered by the blue line. No one of us can survive in the inner part of this sphere, or in the outer space. Despite all films, games, and books about contacts with aliens, and endless journeys across the universe, our present knowledge only allows to suggest that it is most probable that the human being will extinct while in this fine fluid membrane, than to create sustainable artificial environments in the cosmos”. Sometimes, to add some drama, we project the known image of the earth on a wall (the image of the blue sphere), and then we blow a soap bubble explaining that the image gives the false impression that the entire sphere is our home. But our “home” is better represented by the liquid film of the soap bubble (only the film) and then we touch the bubble, exploding it, showing its fragility. In the sequence, we explain that a first reason to understand fluids would be, then, to guarantee the maintenance of the fluidic environment (the film) so that we could also guarantee our survival as much as possible. Further, as we move ourselves and produce our things immersed in fluid, it is interesting to optimize such operations in order to facilitate our survival. Still further, because our organisms interchange heat X Preface and mass in cellular and corporal scales between different fluids, the understanding of these transports permits us to understand the spreading of diseases, the delivering of medicines to cells, and the use of physical properties of fluids in internal treatments. Thus, understanding these transports allows us to improve our quality of life. Finally, the observation of the inner part of the sphere, the outer space and its constituents, shows that many “highly energetic” phenomena behave like the fluids around us. It gives us the hope that the knowledge of fluids can help, in the future, to quantify, reproduce, control and use energy sources similar to those of the stars, allowing us to “move through the cosmos”, to create sustainable artificial environments and to leave this “limited film” when necessary. Of course, this “speech” may be viewed as a sort of escapism, related to a fiction of the future. In fact, the day-by-day activities show that we are spending our time with “more important” things, like fighting among us for the dividends of the next fashion wave (or the next technical wave), the hierarchy among nations, or the hierarchy of the cultures of the different nations. So, fighters, warriors, or generals still seem to be the agents that write our history. But global survival, or, in other words, the guarantee of any future history, will need other agents, devoted to other activities. The hope lies on the generation of knowledge, in which the knowledge about fluids is vital. Context of the present book “Hydrodynamics - Advanced Topics” A quick search in virtual book stores may result in more than one hundred titles involving the word “Hydrodynamics”. Considering the superposition existing with Fluid Mechanics, the number of titles grows much more. Considering all these titles, why try to organize another book on Hydrodynamics? One answer could be that the researchers always try new points of view to understand and treat the problems related to Hydrodynamics. Even a much known phenomenon may be re-explained from a point of view that introduces different tools (conceptual, numerical or practical) into the discussion of fluids. And eventually, a detail shows to be useful, or even very relevant. So, it is necessary to give the opportunity for the different authors to expose their points of view. Among the historically relevant books on Hydrodynamics, some should be mentioned here. For example, the volumes “Hydrodynamics” and “Hydraulics”, by Daniel Bernoulli (1738) and his father, Johann Bernoulli (1743) present many interesting sketches and the analyses that converged to the so called “Bernoulli equation”, later deduced more properly by Leonhard Euler. Although there are unpleasant questions about the authorship of the main ideas, as pointed out by Rouse (1967) and Calero (2008), both books are placed in a “prominent position” in history, because of their significant contributions. The volume written by Sir Horace Lamb (1879), now named “Hydrodynamics”, considers the basic equations, the vortex motion, and tidal waves, among other interesting topics. Considering the classical equations and procedures followed to study fluid motion, the books “Fundamentals of Hydro and Aerodynamics“ and “Applied Hydro and Aerodynamics“ by Prandtl and Tietjens (1934) present the theory and its practical applications in a comprehensive way, [...]... working with Hydrodynamics The book Hydrodynamics - Advanced Topics is organized in the following manner: Part 1: Mathematical Models in Fluid Mechanics Part 2: Biological Applications and Biohydrodynamics Part 3: Detailed Experimental Analyses of Fluids and Flows Part 4: Radiation-, Electro-, Magnetohydrodynamics and Magnetorheology Part 5: Special Topics on Simulations and Experimental Data Hydrodynamics. .. general central moments ( =1, 2, 3…) for the scalar fluctuation f are given by f   1  f 1 n  f 2  1  n   n  1  n   1  n   or, normalizing the th f '    1    1   n    Fp  Fn   1   f    (24) root ( )  f   Fp  Fn   1   n  1  n   1  n     1    1   n   1   f  (25) The functional form of the statistical quantities shown here must be obtained...
