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.

Based on the industry leading short course “Transportation of Solids using Centrifugal Pumps,” founded by Dr. Kenneth Wilson and Graeme Addie, and hosted by the GIW Industries Hydraulic Laboratory, this expanded 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. Stands as an authoritative reference for engineers in the dredging, mining, mineral and chemical processing industries; Incorporates the latest advances in the field, including both theory and practice. Reinforces concepts presented with worked solutions and case studies.
