Book Description
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.

Book Description
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.
