Solid Liquid Two Phase Flow In Centrifugal Pump

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.

Advances in Solid-Liquid Flow in Pipes and its Application focuses on solid-liquid interactions. The selection first takes a look at hydraulic transport of bulky materials and role of lift in the radial migration of particles in a pipe flow. Topics include the technological and economical considerations of transporting materials; lift model and the equations of motion; coefficients of lift and drag; and calculated behavior of particles in a pipe flow. The book then discusses particle and fluid velocities of turbulent flows of suspensions of neutrally buoyant particles; phase-separation phenomena in iso-density, two-phase flows; and transient flow of solid-liquid mixtures in pipes. The text discusses pipeline transportation of coke in petroleum products, including slurry components, hydraulic tests, and hydraulic characteristics of slurry. The book then evaluates the use of heavy media in the pipeline transport of particulate solids. Comparison of pressure gradients and equipment and experimental procedures are highlighted. The selection is a valuable reference for readers interested in solid-liquid interactions.

Slurry Flow: Principles and Practice describes the basic concepts and methods for understanding and designing slurry flow systems, in-plan installations, and long-distance transportation systems. The goal of this book is to enable the design or plant engineer to derive the maximum benefit from a limited amount of test data and to generalize operating experience to new situations. Design procedures are described in detail and are accompanied by illustrative examples needed by engineers with little or no previous experience in slurry transport. The technical literature in this field is extensive: this book facilitates its use by surveying current research results and providing explanations of mechanistic flow models. This discussion of background scientific principles helps the practitioner to better interpret test data, select pumps, specify materials of construction, and choose measuring devises for slurry transport systems. The extensive range of topics covered in Slurry Flow: Principles and practice includes slurry rheology, homogeneous and heterogeneous slurry flow principles, wear mechanisms, pumping equipment, instrumentation, and operating aspects.

The ongoing digitalization of the energy sector, which will make a large amount of data available, should not be viewed as a passive ICT application for energy technology or a threat to thermodynamics and fluid dynamics, in the light of the competition triggered by data mining and machine learning techniques. These new technologies must be posed on solid bases for the representation of energy systems and fluid machinery. Therefore, mathematical modelling is still relevant and its importance cannot be underestimated. The aim of this Special Issue was to collect contributions about mathematical modelling of energy systems and fluid machinery in order to build and consolidate the base of this knowledge.
