L6 Che 1 – You lot did an investigation to find out whether some liquids were polar or non-polar, rather successfully I might add. Anyone still not sure how to spot a polar molecule should have a look at this site.

5 Phy – We looked at how light can be polarised horizontally or vertically using filters and saw what happened when we crossed the filters. Have a look at this site if you’d like to know more about how 3D cinemas work. 

For those of you looking for a different desktop experience, BumpTop Mac is now available for public consumption.

Almost four years ago we got a glimpse of the BumpTop prototype, and the application of physics theory to desktop-based files looked great. Since then, the Windows version has been made available, and the Mac version has been in closed beta (as I’ve mentioned previously). I still like the concept, and it definitely feels like it was made for OS X (versus just a Windows port) which is ideal. To find out more about what BumpTop Mac does, and why (or why not) it may be useful for you, read on.

The good folks at BumpTop brand it as, “Your Mac Desktop, Reinvented,” which I believe is a fair statement. Though I look at it more as what Path Finder did for the Finder — it adds a bunch of features, and makes the standard OS X desktop prettier (in some ways). Read the rest of this entry »

Advancements of fluid flow measuring techniques and of computational methods have led to new ways to treat laminar and turbulent flows. These methods are extensively used these days in research and engineering practise. This also requires new ways to teach the subject to students at higher educational institutions in an introductory manner. The book provides the knowledge to students in engineering and natural science they need to enter fluid mechanics applications in various fields. Analytical treatments are provided based on the Navier-Stokes equations. Introductions are also given into numerical and experimental methods applied to flows.

This is a modern book on fluid mechanics that is written in a way needed these days to teach the subject to students in engineering and science at higher educational institutes. The book is well structured for this purpose and is arranged in a logical teaching sequence of chapters. It is starting with an introductory chapter that contains also the summary of the history of fluid mechanics. In two chapters the basic knowledge in mathematics and physics theory is summarized to provide the background information needed by the students to enter the fluid mechanics. Kinematics of fluid motion is briefly described followed by the complete derivations of the differential form of the continuity and momentum equations, as well as the mechanical and thermal form of the energy equation. Subjects like hydrostatics, similarity theory, potential flows, gas dynamics etc. are treated in an introductory way to lead the students into fluid mechanics. The t_ij terms are introduced to describe the molecular momentum transport and their complete derivation is given by looking at the basis of molecular motions like that in an ideal gas. Subjects like one-dimensional viscous flows, stationary and in stationary, are treated to give the students an introduction into laminar flows. wave mechanics motions in fluids, low Reynolds number flows, high Reynolds number flows and flows with heat transfer are treated to permit the students to get introductory treatments of important parts of fluid mechanics. Introductions are also provided into numerical computations offlows, into turbulence, as well as into measuring techniques as applied in fluid mechanics. In this way, the entire theory and practise of fluid mechanics is treated in the book, providing the student with information needed for more advanced books in specialized subjects of fluid flow treatments.

This book gives an excellent summary of viscous flow and is a valuable addition to any engineers bookshelf. A good knowledge of fluid mechanic fundamentals is essential to understand the material presented. This book is definitely not for a freshman. The author quickly covers the fundamental equations of fluid motion and then proceeds to discuss the viscous flow and boundary layer theory. Laminar boundary layers, transition, turbulent boundary layers and compressible boundary layers each receive a chapter. Each topic is reviewed and examples are given.

The treatment is a little terse, which makes reading the book a tough job. Alot of excellent references are given and I would advise anybody serious about viscous flow to review this material as Whites treatment can be skimpy. The chapter on turbulent flow provides an excellent summary of useful empirical correlations and an introduction to the K-epsilon model. In summary, this is an excellent and reasonably comprehensive reference book(weak on boundary layers in rotating flows), but a poor book to learn from.

This successful textbook emphasizes the unified nature of all the disciplines of Fluid Mechanics as they emerge from the general principles of continuum mechanics. The different branches of Fluid Mechanics, always originating from simplifying assumptions, are developed according to the basic rule: from the general to the specific.

The first part of the book contains a concise but readable introduction into kinematics and the formulation of the laws of mechanics and thermodynamics. The second part consists of the methodical application of these principles to technology. This book is offered to engineers, physicists and applied mathematicians; it can be used for self study, as well as in conjunction with a lecture course.

This second English version is the translation of the very successful seventh German book, significantly expanded by a new chapter about creeping flows. In addition, sections about thin-film flow and flow through porous media are added and thus the book gives a complex introduction to the wide area of fluid mechanics.

Fluid mechanics is the study of how fluids behave and interact under various forces and in various applied situations, whether in liquid or gas state or both. The author compiles pertinent information that are introduced in the more advanced classes at the senior level and at the graduate level. “Advanced Fluid Mechanics” courses typically cover a variety of topics involving fluids in various multiple states (phases), with both elastic and non-elastic qualities, and flowing in complex ways. This new text will integrate both the simple stages of fluid mechanics (“Fundamentals”) with those involving more complex parameters, including Inviscid Flow in multi-dimensions, Viscous Flow and Turbulence, and a succinct introduction to Computational Fluid Dynamics. It will offer exceptional pedagogy, for both classroom use and self-instruction, including many worked-out examples, end-of-chapter problems, and actual computer programs that can be used to reinforce theory with real-world applications.

Professional engineers as well as Physicists and Chemists working in the analysis of fluid behavior in complex systems will find the contents of this book useful.All manufacturing companies involved in any sort of systems that encompass fluids and fluid flow analysis (e.g., heat exchangers, air conditioning and refrigeration, chemical processes, etc.) or energy generation (steam boilers, turbines and internal combustion engines, jet propulsion systems, etc.), or fluid systems and fluid power (e.g., hydraulics, piping systems, and so on)will reap the benefits of this text.

Offers detailed derivation of fundamental equations for better comprehension of more advanced mathematical analysis.

Provides groundwork for more advanced topics on boundary layer analysis, unsteady flow, turbulent modeling, and computational fluid dynamics.

This book is intended to serve as a unique and comprehensive textbook for scientists and engineers as well as advanced students in thermo-fluid courses. It provides an intensive monograph essential for understanding dynamics of ideal fluid, Newtonian fluid, non-Newtonian fluid and magnetic fluid. These distinct, yet intertwined subjects are addressed in an integrated manner. It starts with coherent treatment of fundamental continuum mechanics, with an emphasis on the intrinsic angular momentum, by which the concepts of ferrohydrodynamics are progressively built up, and serve as a foundation for later development.

Flows of ideal and Newtonian fluids are followed by a detailed presentation of basic continuum equations for applications of fluid engineering, which cover the design and operations of various turbomachines, heat exchangers and flow elements. The study of the deformation and flow of matter, namely rheology, is discussed primarily with regard to the stresses generated during the flow of complex materials, which are represented by viscoelastic fluids. Throughout the book, the first priority is to illustrate the utilization of constitutive equations (relations) in order to facilitate an understanding of the physical flow phenomena and mechanisms. Moreover, it enables readers to classify flows and specific engineering problems, which can then be identified and formulated.

In order to make the book self-contained, many exercises and problems are provided for each chapter in addition to the numerous pedagogical aids that have been incorporated throughout. The intention is to facilitate the reader to compose their knowledge into a better understanding of both the theoretical andapplicable aspects of fluid engineering.
