Each year, universities and research centres – most particularly the major space agencies such as NASA, ESA, and NASDA – devote a vast amount of time and money into the research of materials behaviour and production in microgravity. Recently, the possibility of creating special alloys, inorganic and organic crystals, as well as biological (living) tissues in this condition has been investigated. Fluids, Materials and Microgravity provides a solid basis of established knowledge – through literature, fundamental studies, experimental methods, numerical (basic and sophisticated) techniques – as well as the latest in research advancements. Important for the prediction of material behaviour when exposed to the environment of space, this book explores the new knowledge provided by microgravity-based studies in producing unique inorganic, and organic materials on Earth (and in designing related new technological processes). A vital resource for any scientists interested in the understanding and modelling of the new important physical mechanisms disclosed by microgravity research, and in their possible effect on the production and behaviour of materials both in space and on Earth. A vital resource for any scientists interested in the effect of microgravity on the production and behaviour of materials. - Covers typical fluid-dynamic disturbances which can affect the behaviour and final quality of materials both in space and on Earth, and possible strategies to contain their effects - Thorough attention is devoted to the most promising and innovative technological processes provided by microgravity experimentation - Information is provided through application-based engineering models, as well as mathematical frameworks, to facilitate a deeper understanding of physical mechanisms

In a microgravity experiment, the conditions prevalent in fluid phases can be substantially different from those on the ground and can be exploited to improve different processes. Fluid physics research in microgravity is important for the advancement of all microgravity scients: life, material, and engineering. Space flight provides a unique laboratory that allows scientists to improve their understanding of the behaviour of fluids in low gravity, allowing the investigation of phenomena and processes normally masked by the effects of gravity and thus difficult to study on Earth. Physics of Fluids in Microgravity provides a clear view of recent research and progress in the different fields of fluid research in space. The topics presented include bubles and drops dynamics, Maragoni flows, diffustion and thermodiffusion, solidfication,a nd crystal growth. The results obtained so far are, in some cases, to be confirmed by extensive research activities on the International Space station, where basic and applied microgravity experimentation will take place in the years to come.

Thermal Convection - Patterns, Stages of Evolution and Stability Behavior provides the reader with an ensemble picture of the subject, illustrating the state-of-the-art and providing the researchers from universities and industry with a basis on which they are able to estimate the possible impact of a variety of parameters. Unlike earlier books on the subject, the heavy mathematical background underlying and governing the behaviors illustrated in the text are kept to a minimum. The text clarifies some still unresolved controversies pertaining to the physical nature of the dominating driving force responsible for asymmetric/oscillatory convection in various natural phenomena and/or technologically important processes and can help researchers in elaborating and validating new, more complex models, in accelerating the current trend towards predictable and reproducible natural phenomena and in establishing an adequate scientific foundation to industrial processes. Thermal Convection - Patterns, Stages of Evolution and Stability Behavior is intended as a useful reference guide for specialists in disciplines such as the metallurgy and foundry field and researchers and scientists who are now coordinating their efforts to improve the quality of semiconductor or macromolecular crystals. The text may also be of use to organic chemists and materials scientists, atmosphere and planetary physicists, as well as an advanced level text for students taking part in courses on the physics of fluids, fluid mechanics, the behavior and evolution of non-linear systems, environmental phenomena and materials engineering.

The large crystals of semiconducting and superconducting materials used for electronic and optical devices are usually grown from the melt by Czochralski or Bridgman method and their quality is significantly affected by the melt flow and related heat and mass transfer. Recent intensive research activities in this area covering crystal growth in microgravity, crystal growth of superconducting materials, crystal growth in high pressure, the commercial development of pullers that can produce crystals with large diameters etc. have substantially raised the expectation for numerous new practical applications.
