In this book the CFD analysis of a centrifugal pump is done using k-ε turbulent modeling and SIMPLEC algorithm from which the velocity and pressure contours are plotted for different operating conditions. In this work the mass flow rate is varied three times for two different fluids that are water and fuel oil. First the mass flow rate is decreased by 10% from the initial value of mass flow rate and then increased by 10% from the initial value of mass flow rate. Using the results of varying mass flow rate the efficiency at different mass flow rate is calculated. The results are compared with the theoretical results. Then the theoretical and software results are plotted in the operating characteristics curves and are verified. The deviation produced among them nearly 10% to 15 % is permissible. Then the rotational speed (RPM) is changed by decreasing and increasing by 10% and results are compared with the theoretical results and verified through characteristics curves. After the flow analysis the maximum pressure acting on the blades for the maximum efficiency in case of water and fuel oil are calculated from CFD analysis and the fatigue analysis (FEA) of the centrifugal pump

With the right broker, and just a few hundred dollars or pounds, anyone can become a leveraged trader. The products and tools needed are accessible to all: FX, a margin account, CFDs, spread-bets and futures. But this level playing field comes with great risks. Trading with leverage is inherently dangerous. With leverage, losses and costs – the two great killers for traders – are magnified. This does not mean leverage must be avoided altogether, but it does mean that it needs to be used safely. In Leveraged Trading, Robert Carver shows you how to do exactly that, by using a trading system. A trading system can be employed to tackle those twin dangers of serious losses and high costs. The trading systems introduced in this book are simple and carefully designed to use the correct amount of leverage and trade at a suitable frequency. Rob shows how to trade a simple Starter System on its own, on a single instrument and with a single rule for opening positions. He then moves on to show how the Starter System can be adapted, as you gain experience and confidence. The system can be diversified into multiple instruments and new trading rules can be added. For those who wish to go further still, advice on making more complex improvements is included: how to develop your own trading systems, and how to combine a system with your own human judgement, an approach Robert has nicknamed Semi-Automatic Trading. For those trading with leverage, looking for a way to take a controlled approach and manage risk, a properly designed trading system is the answer. Pick up Leveraged Trading and learn how.

Computational Fluid Dynamics (CFD) and structural analysis play a significant role in the development of technical devices, building construction, weather predictions, biochemistry processes modeling, and in many other fields. With regard to increase computational power increase and improvements in computer modeling techniques, it is expected that the numerical simulations will prevail the traditional methods, such as the experiments and analytical solutions, in the near future. Behind computer modeling, there are complex mathematical apparatuses, physical theories, chemical reactions, etc. Together, these factors make it difficult to understand and use CFD and structural analysis. This book attempts to systematize and provide an easy explanation of computer modeling.

This book is a guide to numerical methods for solving fluid dynamics problems. The most widely used discretization and solution methods, which are also found in most commercial CFD-programs, are described in detail. Some advanced topics, like moving grids, simulation of turbulence, computation of free-surface flows, multigrid methods and parallel computing, are also covered. Since CFD is a very broad field, we provide fundamental methods and ideas, with some illustrative examples, upon which more advanced techniques are built. Numerical accuracy and estimation of errors are important aspects and are discussed in many examples. Computer codes that include many of the methods described in the book can be obtained online. This 4th edition includes major revision of all chapters; some new methods are described and references to more recent publications with new approaches are included. Former Chapter 7 on solution of the Navier-Stokes equations has been split into two Chapters to allow for a more detailed description of several variants of the Fractional Step Method and a comparison with SIMPLE-like approaches. In Chapters 7 to 13, most examples have been replaced or recomputed, and hints regarding practical applications are made. Several new sections have been added, to cover, e.g., immersed-boundary methods, overset grids methods, fluid-structure interaction and conjugate heat transfer.
