Book excerpt: 1,1 Applications of Slurry Transport Vast tonnages are pumped every year in the form of solid-liquid mixtures, known as slurries. The application which involves the largest quantities is the dredging industry, continually maintaining navigation in harbours and rivers, altering coastlines and winning material for landfill and construction purposes. As a single dredge may be required to maintain a throughput of 7000 tonnes of slurry per hour or more, very large centrifugal pumps are used. Figures 1-1 and 1-2 show, respectively, an exterior view of this type of pump, and a view of a large dredge-pump impeller (Addie & Helmley, 1989). The manufacture of fertiliser is another process involving massive slur- transport operations. Li Florida, phosphate matrix is recovered by huge draglines in open-pit mining operations. It is then slurried, and pumped to the wash plants through pipelines with a typical length of about 10 kilometres. Each year some 34 million tonnes of matrix are transported in this manner. This industry employs centrifugal pumps that are generally smaller than those used in large dredges, but impeller diameters up to 1. 4 m are common, and drive capacity is often in excess of 1000 kW. The transport distance is typically longer than for dredging applications, and Chapter 1 Figure LI. Testing a dredge pump at the GIW Hydraulic Laboratory Figure 1. 2.

Download or read book Slurry Transport Using Centrifugal Pumps written by Robert Visintainer and published by Springer Nature. This book was released on 2023-04-03 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the industry leading short course of the same name hosted by the GIW Industries Hydraulic Laboratory and founded by Dr. Roland Clift and Graeme Addie, who together with Dr. Ken Wilson continued its development and authored the first edition of this textbook. This fourth edition has been extensively updated by the international team of engineers and authors who inherited this legacy and continue its development to the present day. Focusing on the hydraulic design of slurry pipelines, the pumps that power them, and the interactions between pumps and systems, it retains the classroom tested balance of theoretical development and practical engineering which have made it a slurry transport classic. The topics covered are important to slurry system engineers for the optimization of new designs, as well as the operators of existing systems, who may need to calculate and plan for changing conditions from day to day. Updates to the fourth edition include: · Careful formulation of the theoretical concepts, providing greater clarity of slurry flow dynamics, including a new chapter on the principles and characterization of slurry flows. · Expansion of the 4-Component Models for settling slurry pipeline flow and pump solids effect, based on an extensive series of full-sized tests. · An expanded treatment of complex slurries, including a broader discussion of non-Newtonian fluids and their interaction with coarse particles. · A new chapter on test methods, presenting an overview of slurry system instrumentation, modern techniques for characterizing slurry rheology, and practical advice for planning and executing a slurry test. · An overview of advances in the computational modeling of slurries, including an in-depth parametric study of slurry pump wear and operating cost. The authors highlight methods for achieving energy efficiency, which are crucial to the effective use of scarce resources, given the foundational role of slurry transport systems in the energy intensive industries of mining and dredging. Key concepts are supported with case studies and worked examples. Slurry Transport Using Centrifugal Pumps, fourth edition, is both methodical and in-depth. It is ideal as a teaching tool for classroom or self-directed learning domains, and valuable as a design guide for engineer practitioners at all experience levels.

Download or read book Inclusion of Blockage Effects in Inverse Design of Centrifugal Pump Impeller Blades written by Rahul Singh and published by . This book was released on 2015 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and analysis of turbo-machinery are complex tasks due to the complexity of the geometry and the flow physics. The application of various computational tools to evaluate the performance of a specified geometry is commonly designated as a direct method. In a direct design approach designer's experience and talent are vital factors to reduce the number of trials while in an inverse design approach designer needs to prescribe the performance function as an input. It is often desirable to apply the inverse design approach, in which performance parameters are prescribed in the form of performance functions, the so called loading distribution, to obtain the corresponding geometry of pump as the result. At the start of an inverse design technique, the desired performance functions are prescribed as input quantities, and an initial, guessed shape of the impeller blade geometry is changed iteratively to arrive at the converged shape. The present study has developed a procedure for inverse design of a two-dimensional centrifugal pump impeller blades using the computational fluid dynamics (CFD) software, OpenFOAM (an open-source CFD software) and FLUENT. In the current work, the Gambit software is used for geometry development, domain decomposition, and grid generation. In this thesis, OpenFOAM is used to solve for the in-viscid flow in the passage formed by two adjacent blades of a pump. FLUENT is used to solve full Navier-Stokes equations to calculate blockage factor distribution along the meridional plane. The evolving blade shapes are computed by using flow tangency condition; the viscous effects in the mean flow are introduced indirectly by using the blockage effects from viscous simulations. Polynomial curve fitting techniques is used to generate the loading distribution of circulation. During each step of the current inverse design technique, the flow field analysis and blade shape calculations are performed alternately, while satisfying the boundary condition based on the loading distribution function at each step, until a fully converged solution is achieved. All the steps involved in the technique are automated by linking the individual codes in a Linux shell script. The blade shape and flow domain changes with each iteration, which means the grid also changes with each iteration. It is very time consuming to generate grid manually at each iteration, so a journal file is written in Gambit, which is executed automatically with each iteration and generates a mesh. The generated mesh is imported in OpenFOAM, where the flow analysis is done using the laplacianFOAM module of OpenFOAM, using boundary conditions based on the prescribed performance function. The tentative performance function is obtained using the circulation distribution, which is accommodated by modifying the laplacianFOAM solver. The viscous flow is solved between passages of two consecutive blades of the impeller to find the blockage factor distribution, using FLUENT. The current inverse design process is verified for a logarithmic spiral blade. Thus, the current work gives a good approach of incorporating blockage via viscous effects in the mean flow for an impeller geometry using OpenFOAM and FLUENT.

Download or read book Centrifugal Pumps written by Johann Friedrich Gülich and published by Springer. This book was released on 2014-10-24 with total page 1146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an unparalleled, up-to-date, in-depth treatment of all kinds of flow phenomena encountered in centrifugal pumps including the complex interactions of fluid flow with vibrations and wear of materials. The scope includes all aspects of hydraulic design, 3D-flow phenomena and partload operation, cavitation, numerical flow calculations, hydraulic forces, pressure pulsations, noise, pump vibrations (notably bearing housing vibration diagnostics and remedies), pipe vibrations, pump characteristics and pump operation, design of intake structures, the effects of highly viscous flows, pumping of gas-liquid mixtures, hydraulic transport of solids, fatigue damage to impellers or diffusers, material selection under the aspects of fatigue, corrosion, erosion-corrosion or hydro-abrasive wear, pump selection, and hydraulic quality criteria. As a novelty, the 3rd ed. brings a fully analytical design method for radial impellers, which eliminates the arbitrary choices inherent to former design procedures. The discussions of vibrations, noise, unsteady flow phenomena, stability, hydraulic excitation forces and cavitation have been significantly enhanced. To ease the use of the information, the methods and procedures for the various calculations and failure diagnostics discussed in the text are gathered in about 150 pages of tables which may be considered as almost unique in the open literature. The text focuses on practical application in the industry and is free of mathematical or theoretical ballast. In order to find viable solutions in practice, the physical mechanisms involved should be thoroughly understood. The book is focused on fostering this understanding which will benefit the pump engineer in industry as well as academia and students.
