Book Description
The book provides the theoretical fundamentals on turbulence and a complete overview of turbulence models, from the simplest to the most advanced ones including Direct and Large Eddy Simulation. It mainly focuses on problems of modeling and computation, and provides information regarding the theory of dynamical systems and their bifurcations. It also examines turbulence aspects which are not treated in most existing books on this subject, such as turbulence in free and mixed convection, transient turbulence and transition to turbulence. The book adopts the tensor notation, which is the most appropriate to deal with intrinsically tensor quantities such as stresses and strain rates, and for those who are not familiar with it an Appendix on tensor algebra and tensor notation are provided.

Book Description
This book gathers ten thermofluid dynamics problems involving the use of analytical solutions. All these problems have been encountered by the author during his research activity; some of the solutions are his own contributions, while others either are classic literature results or can be derived from them. The physical phenomena involved range from pure hydrodynamics to flow with heat or mass transfer, two-phase flow, and magnetohydrodynamics. The problems discussed are not canonical problems; they are rarely found in textbooks, and often exhibit surprising, or even paradoxical, solutions. The potential readership of the book includes students, teachers and scientists in science and engineering interested in fluid dynamics and heat/mass transfer: to them it may offer food for thought, suggestions for lectures or tutorials and ideas for further original developments.

Book Description
Combining previously unconnected computational methods, this monograph discusses the latest basic schemes and algorithms for the solution of fluid, heat and mass transfer problems coupled with electrodynamics. It presents the necessary mathematical background of computational thermo-fluid dynamics, the numerical implementation and the application to real-world problems. Particular emphasis is placed throughout on the use of electromagnetic fields to control the heat, mass and fluid flows in melts and on phase change phenomena during the solidification of pure materials and binary alloys. However, the book provides much more than formalisms and algorithms; it also stresses the importance of good, feasible and workable models to understand complex systems, and develops these in detail. Bringing computational fluid dynamics, thermodynamics and electrodynamics together, this is a useful source for materials scientists, PhD students, solid state physicists, process engineers and mechanical engineers, as well as lecturers in mechanical engineering.

Book Description
It is recognized that the study of mechanical engineering is built of a number of engineering sciences, some of which are of basic nature whereas some other are of applied nature. "Basic Thermodynamics" and "Basic Fluid Dynamics" are probably the two most important basic engineering sciences in the build of a Mechanical Power Engineer. In applied mechanical power engineering sciences, the principles introduced and analysed in these two basic sciences are common divisors. In other words, we may look at these two branches of basic engineering sciences as two legs on which Mechanical Power Engineering applications appear to stand. The science of "Basic Thermodynamics " is based mainly on a number of basic principles (in the form of laws) that lead to a number of equations describing and governing the behavior of several mechanical power systems. It is therefore of particular importance to introduce and analyse such equations. It is also essential to relate these principles and equations to each other and, whenever possible, to pertinent phenomena and applications. This may be achieved via worked examples that stem from from engineering practice. The science of "Basic Fluid Dynamics" is another basic engineering science of equal importance to "Basic Thermodynamics". The principles introduced and analysed by this basic science find applications in almost all applied mechanical power engineering sciences. Examples of these applied sciences are "Applied Thermodynamics", "Applied Fluid Dynamics", "Combustion Engineering"," Turbo-machinery", "Refrigeration and Air-conditioning", "Power Plants", "Gas dynamics". "Propulsion systems" ….etc. Because of the close inter-relation between the science of basic thermodynamics and the science of basic fluid dynamics, it has become a common practice to contained both sciences in one textbook under the title “Basic Thermo/fluid Dynamics” (the title of the present textbook). The present textbook on "Basic Thermo/fluid Dynamics" has been divided into distinct parts: A and B. In part A, we concentrate on "Basic Thermodynamics", attempting to present, with as much clarity as possible, the basic principles therein and giving several worked examples for the sake of clarification. In part B, we concentrate on "Basic Fluid Dynamics", applying the same philosophy as in Part A. In this part also, a special section (in chapter five) containing a rather concise manipulation of the applied science of "Compressible Fluid (Gas) Dynamics" is presented, being an important combined application of the basic principles discussed in thermodynamics and fluid dynamics. Moreover, It was felt by the authors that it is particularly important to include this section on gas dynamics, since, in spite of being applied in nature, it is regarded by many as basic more than applied. The last chapter of Part A and chapter five of Part B cover some important engineering applications of the principles given apriori. Each of these applications may be looked upon as a brief exposition of an applied engineering science carrying the title of the application under consideration. This was felt imperative to the advantage hopefully to be gained by the student. The authors are indebted to their colleague Dr. Mohammad S.H. Emeara of the Mechanical Power Engineering Department, Zagazig University, for assisting with part of the illustrations and wish to thank him for rendering this assistance in the early stages of preparation of this textbook.

Book Description
Turbulent reactive flows are of common occurrance in combustion engineering, chemical reactor technology and various types of engines producing power and thrust utilizing chemical and nuclear fuels. Pollutant formation and dispersion in the atmospheric environment and in rivers, lakes and ocean also involve interactions between turbulence, chemical reactivity and heat and mass transfer processes. Considerable advances have occurred over the past twenty years in the understanding, analysis, measurement, prediction and control of turbulent reactive flows. Two main contributors to such advances are improvements in instrumentation and spectacular growth in computation: hardware, sciences and skills and data processing software, each leading to developments in others. Turbulence presents several features that are situation-specific. Both for that reason and a number of others, it is yet difficult to visualize a so-called solution of the turbulence problem or even a generalized approach to the problem. It appears that recognition of patterns and structures in turbulent flow and their study based on considerations of stability, interactions, chaos and fractal character may be opening up an avenue of research that may be leading to a generalized approach to classification and analysis and, possibly, prediction of specific processes in the flowfield. Predictions for engineering use, on the other hand, can be foreseen for sometime to come to depend upon modeling of selected features of turbulence at various levels of sophistication dictated by perceived need and available capability.

Book Description
Infrared thermography is a measurement technique that enables to obtain non intrusive measurements of surface temperatures. One of the interesting features of this technique is its ability to measure a full two dimensional map of the surface temperature and for this reason it has been widely used as a flow visualization technique. Since the temperature measurements can be extremely accurate it is possible, by using a heat flux sensor, also to measure convective heat transfer coefficient distributions on a surface making the technique de facto quantitative. This book, starting from the basic theory of infrared thermography and heat flux sensor guides, both the experienced researcher and the young student, in the correct application of this powerful technique to various practical problems. A significant number of examples and applications are also examined in detail.
