Рост Кристаллоь / Rost Kristallov / Growth of Crystals by A. A. Chernov Pdf

Volumes 11 and 12 contain the papers read at the Fourth All-Union Conference on Crystal Growth in Tsakhkadzor, September 17-22, 1972; this volume contains papers on crystal growth from melts, from low-temperature solutions, hydrothermal solutions, and hot solutions, and also from the gas state, including processes involving reactions. In addition, there are papers on crystal perfection in relation to conditions of formation and the effects of electric and mag netic fields on crystallization. These papers reflect researches directed to the development and industrial production of perfect crystals required for advanced techniques in solid-state physics and chemistry, as well as for other purposes such as novel materials. There are many different scientific and technical problems in producing large perfect single crystals, and advances in this area made in the USSR and elsewhere are reflected in the papers in both volumes. On the one hand, any particular defective structure in a crystal originates from some mechanism and growth conditions; in particular, inclusions are trapped on account of the physicochemical parameters of the melt, the surface processes, and the sta bility of the growth front under particular crystallization conditions. Further, impurity trap ping is decisively influenced by the surface kinetics, growth-front stability, composition and structure of the boundary layer, any complexes present in the liquid, and (of course) the crys tallochemical relationships between the impurity and the crystal.

Рост Кристаллоь / Rost Kristallov / Growth of Crystals by A. A. Chernov Pdf

The Growth of Crystals series was begun in 1957 by A. V. Shubnikov and . N. N. SheftaP with the publication of the first volume. which contained the proceedings of the First All-Union Conference on Crystal Growth. The initiative and considerable efforts of the principal editor of the entire series. N. N. Sheftal', and his assistants led over the next 15 years to the publica tion of ten volumes which have assumed a leading position among the numerous books on crys tal growth. It has become traditional in this series to adopt a broad approach to crystal growth problems, and this approach is continued in Volumes 11 and 12, which are composed mainly of papers presented at the Fourth All-Union Conference on Crystal Growth in Tsakhkadzor. September 17-22, 1972. These papers, presented by both Soviet and foreign workers, deal with crystal growth processes. growth methods. and crystal perfection. Many of the papers reflect the tendency for our knowledge of crystallization processes to become increasingly more fundamental. with emphaSis on quantitative treatments. There are some extremely difficult problems in this approach. especially when the requirements of practical uses are envisaged. and many of these are discussed in various ways in these two volumes. These topics include detailed theoretical and experimental analysis of cooperative phenomena in crystallization. with emphasis not only on statistical thermodynamics but also statistical kinetics. This approach involves research on the structure and properties of phase boundaries. including the composition and structure of surface layers in liquids.

РОСТ КРИСТАЛЛОВ/Rost Kristallov/Growth of Crystals by N. N. Sheftal',E. I. Givargizov Pdf

For 50 years the Fedorov Institute of Crystallography, Mineralogy, and Petrography at Leningrad Mining Institute has held annual memorial meetings for E. S. Fedorov. Immediate ly after the jubilee meeting (May 21-24, 1969), the Fedorov All-Union Symposium on Crystal Growth was held, and the proceedings of that symposium constitute Volume 9 of Growth of Crystals. The symposium surveyed the advances made in the USSR in those aspects of growth con cerned mainly with morphology and structure in natural crystals or closely related artificial ones, work which confirmed their relation to E. S. Fedorov and to mineralogical crystallogra phy. Crystallography is one of the older branches of natural science but has recently under gone a striking rejuvenation on account of new methods and new concepts. Photogoniometric methods have been developed in goniometry, while crystal optics has found new lines of ad vance in electrooptics and techniques in the ultraviolet and far infrared regions. Morphologic studies now use a vast range of techniques, from the hand lens to the electron microscope or cinemicrography. X-ray analysis is steadily becoming more automatic, and fast computers are used with accelerated methods of structure interpretation. Crystal growth is one of the younger divisions of crystallography; previously t it had been of interest only in experimental mineralogy, but now it is an important branch of science and technology with close relations to industry.

Two-Fluid Model Stability, Simulation and Chaos by Martín López de Bertodano,William Fullmer,Alejandro Clausse,Victor H. Ransom Pdf

This book addresses the linear and nonlinear two-phase stability of the one-dimensional Two-Fluid Model (TFM) material waves and the numerical methods used to solve it. The TFM fluid dynamic stability is a problem that remains open since its inception more than forty years ago. The difficulty is formidable because it involves the combined challenges of two-phase topological structure and turbulence, both nonlinear phenomena. The one dimensional approach permits the separation of the former from the latter.The authors first analyze the kinematic and Kelvin-Helmholtz instabilities with the simplified one-dimensional Fixed-Flux Model (FFM). They then analyze the density wave instability with the well-known Drift-Flux Model. They demonstrate that the Fixed-Flux and Drift-Flux assumptions are two complementary TFM simplifications that address two-phase local and global linear instabilities separately. Furthermore, they demonstrate with a well-posed FFM and a DFM two cases of nonlinear two-phase behavior that are chaotic and Lyapunov stable. On the practical side, they also assess the regularization of an ill-posed one-dimensional TFM industrial code. Furthermore, the one-dimensional stability analyses are applied to obtain well-posed CFD TFMs that are either stable (RANS) or Lyapunov stable (URANS), with the focus on numerical convergence.

Theoretical Fluid Dynamics by Achim Feldmeier Pdf

This textbook gives an introduction to fluid dynamics based on flows for which analytical solutions exist, like individual vortices, vortex streets, vortex sheets, accretions disks, wakes, jets, cavities, shallow water waves, bores, tides, linear and non-linear free-surface waves, capillary waves, internal gravity waves and shocks. Advanced mathematical techniques ("calculus") are introduced and applied to obtain these solutions, mostly from complex function theory (Schwarz-Christoffel theorem and Wiener-Hopf technique), exterior calculus, singularity theory, asymptotic analysis, the theory of linear and nonlinear integral equations and the theory of characteristics. Many of the derivations, so far contained only in research journals, are made available here to a wider public.

Shallow Water Hydraulics by Oscar Castro-Orgaz,Willi H. Hager Pdf

This book presents the theory and computation of open channel flows, using detailed analytical, numerical and experimental results. The fundamental equations of open channel flows are derived by means of a rigorous vertical integration of the RANS equations for turbulent flow. In turn, the hydrostatic pressure hypothesis, which forms the core of many shallow water hydraulic models, is scrutinized by analyzing its underlying assumptions. The book’s main focus is on one-dimensional models, including detailed treatments of unsteady and steady flows. The use of modern shock capturing finite difference and finite volume methods is described in detail, and the quality of solutions is carefully assessed on the basis of analytical and experimental results. The book’s unique features include: • Rigorous derivation of the hydrostatic-based shallow water hydraulic models • Detailed treatment of steady open channel flows, including the computation of transcritical flow profiles • General analysis of gate maneuvers as the solution of a Riemann problem • Presents modern shock capturing finite volume methods for the computation of unsteady free surface flows • Introduces readers to movable bed and sediment transport in shallow water models • Includes numerical solutions of shallow water hydraulic models for non-hydrostatic steady and unsteady free surface flows This book is suitable for both undergraduate and graduate level students, given that the theory and numerical methods are progressively introduced starting with the basics. As supporting material, a collection of source codes written in Visual Basic and inserted as macros in Microsoft Excel® is available. The theory is implemented step-by-step in the codes, and the resulting programs are used throughout the book to produce the respective solutions.
