Download or read book Centrifugal Pump Performance Under Simulated Two phase Flow Conditions PWR written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Test results are presented from centrifugal (mixed-flow) pump performance testing conducted at the Idaho National Engineering Laboratory (INEL) using nitrogen-water flow to simulate steam-water two-phase conditions. The results are compared with the predictions of the RELAP4/MOD6 pump performance model which is based on experimental data obtained from tests conducted on a small (radial-flow) pump in the Semiscale facility. The purpose of this investigation is to obtain the two-phase characteristics of a mixed-flow pump and evaluate the prediction capability of the pump model commonly used to analyze the thermal-hydraulic response when applied to a postulated loss-of-coolant accident in a light water reactor.
Download or read book Solid Liquid Two Phase Flow in Centrifugal Pump written by Zuchao Zhu and published by Springer. This book was released on 2024-05-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book conducts a systematic study on internal flow characteristics and performance of centrifugal pump for solid–liquid mixed transportation. First, the applicability of the computational model for two-phase flow is analyzed. Then the relationship between the two-phase flow characteristics and wall wear in the pipeline is revealed. And the flow characteristics in centrifugal pumps are analyzed in relation to conveying performance and wall wear. Finally, the engineering application calculation of the mixed transportation pump with different impeller structures is carried out. The target audience of this book is researchers who perform calculations and engineering applications of solid–liquid two-phase pumps. This book considers the influence of the particle size on the force magnitude of the particles and analyzes the applicability of different solid–liquid two-phase calculation models. Considering the different motion trajectories of particles colliding with dry wall, wet wall, stationary wall, and moving wall, visual experiments are used to study the collision rebound model of different walls. The collision rebound model is applied to the numerical simulation of solid–liquid mixed transport.
Download or read book Hydrodynamics of Pumps written by Christopher E. Brennen and published by Cambridge University Press. This book was released on 2011-03-28 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students. It examines the fluid dynamics of liquid turbomachines, particularly pumps, focusing on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows and turbomachinery, basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps - discussed in the three final chapters. The book is richly illustrated and includes many practical examples.
Download or read book First Quadrant Two Phase Flow in Centrifugal Pumps written by Raymond David Zegley and published by . This book was released on 1977 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: A pump system was built and instrumented on which tests were performed yielding single- and two-phase actual pump characteristics for first-quadrant operation (forward flow and forward rotation) of two different centrifugal impellers mounted in a simple two-dimensional volute. Theoretical single- and two-phase pump characteristics were determined from the impeller geometry, the Euler equation, and the use of the two-phase flow function. The head-loss ratio, the loss of head in two-phase flow dividied by the loss of head in single-phase flow, was then plotted versus void fraction. The results were compared to an earlier theory proposed which predicted the head-loss ratio to be primarily a function of void fraction. These results indicate that the head-loss ratio is a function of flow coefficient as well as void fraction. Flow-visualization studies were also conducted and revealed that flow regime inside the blade passages can be different from either the inlet or outlet flow regimes, and greatly affects pump performance. Further experimentation, on a more efficient system employing higher-specific-speed impellers, is recommended to study more closely the effect of flow coefficient, flow regime and void fraction upon two-phase pump performance.

New additions: - A separate chapter on "Vibrations on vertical pumps". - Measurements of hydraulic exciter and impeller reaction forces - Alternating stresses and fatigue fractures of impellers - a critical study on the accuracy of numerical flow calculations of pumps - Design of inlet housings and double spirals for multistage pumps.
Download or read book Selected Problems in Fluid Flow and Heat Transfer written by Artur J. Jaworski and published by MDPI. This book was released on 2019-09-20 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid flow and heat transfer processes play an important role in many areas of science and engineering, from the planetary scale (e.g., influencing weather and climate) to the microscopic scales of enhancing heat transfer by the use of nanofluids; understood in the broadest possible sense, they also underpin the performance of many energy systems. This topical Special Issue of Energies is dedicated to the recent advances in this very broad field. This book will be of interest to readers not only in the fields of mechanical, aerospace, chemical, process and petroleum, energy, earth, civil ,and flow instrumentation engineering but, equally, biological and medical sciences, as well as physics and mathematics; that is, anywhere that “fluid flow and heat transfer” phenomena may play an important role or be a subject of worthy research pursuits.

Book excerpt: The second edition of a comprehensive textbook that introduces turbomachinery and gas turbines through design methods and examples. This comprehensive textbook is unique in its design-focused approach to turbomachinery and gas turbines. It offers students and practicing engineers methods for configuring these machines to perform with the highest possible efficiency. Examples and problems are based on the actual design of turbomachinery and turbines. After an introductory chapter that outlines the goals of the book and provides definitions of terms and parts, the book offers a brief review of the basic principles of thermodynamics and efficiency definitions. The rest of the book is devoted to the analysis and design of real turbomachinery configurations and gas turbines, based on a consistent application of thermodynamic theory and a more empirical treatment of fluid dynamics that relies on the extensive use of design charts. Topics include turbine power cycles, diffusion and diffusers, the analysis and design of three-dimensional free-stream flow, and combustion systems and combustion calculations. The second edition updates every chapter, adding material on subjects that include flow correlations, energy transfer in turbomachines, and three-dimensional design. A solutions manual is available for instructors.
