Available in PDF, EPUB and Kindle. Book excerpt: A pump is a mechanical device that converts mechanical energy into hydraulic energy. The aim of the current work is to examine the behavior of fluid flow inside a rotary sliding vane pump and assessing the performance by studying the effect of change of the rotational speed, number of vanes and the radial clearance gap size between vane tips and stator surface on the performance of the pump. The commercial finite-volume solver ANSYS Fluent was used to build a 3D model of the pump and simulate the flow behavior in it with an additional C-language source code for the description of the dynamic mesh motion. Pump flow was studied using lubricating oil, 5W-30, as the working fluid. Several computational configurations were used for the numerical simulation.

Book Synopsis Numerical Simulations of Centrifugal Pump Efficiency by : Haoyu Wang
Download or read book Numerical Simulations of Centrifugal Pump Efficiency written by Haoyu Wang and published by . This book was released on 2012 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been recognised that some of the vital characteristics such as flow patterns and pressure fluctuations of the centrifugal pump will affect the overall pump efficiency. However, most of past research based on theoretical analysis or experiments, which are time consuming and expensive. With the development of computer science, it is possible now to investigate the three dimensional unsteady flow patterns in the centrifugal pump. Then the study can be applied to establish the correlation between the pump characteristics and efficiency numerically. This thesis describes some experiments which establish the performance curve of a particular commercial centrifugal pump, which then be used as the basic data for the numerical results to be compared with. The modal test of this centrifugal pump was conducted for both its components and assembly to verify the structural rigid assumption in the numerical simulation. Both static numerical method (Frozen Rotor) and transient numerical method (Sliding Mesh) were used in this thesis. The key findings are summarized as follows: From the results obtained by Frozen Rotor method, it can be seen that the general trend of global properties including water head and pump efficiency were captured well while there existed some differences when compared them with experimental data. This was possibly due to the limitations of Frozen Rotor method to predict unsteady flow phenomenon. When the Sliding Mesh method applied, the results indicate that: First of all, it was possible that the position of the large vorticity zone could be a factor which would result in the change of the pump efficiency. Secondly, if the helical region distributed uniformly, the pump is more likely to operate at BEP. On the other hand, the pump efficiency would drop if non-uniform helical regions observed. Finally, it can be found that the pump efficiency decreases as the magnitude of dynamic pressure increases. In other words, more energy has been used to generate vibration when the pump operates at off-design conditions. A similar trend can be observed for the pump efficiency, the magnitude of dynamic pressure, the amplitude of velocity and the vibration energy. The minimum of these properties can be seen when the pump operated under design condition while an increase of these properties can be observed for off-design pump operating condition. This corresponds to the statement that if more energy had been used to generate vibration, less pump efficiency can be expected. An empirical correlation between the pump vibration and efficiency then has been established in this project.

This book was released on 2024-01-01 with total page 877 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new proceedings discusses developments in air, gas and refrigeration compressors, vacuum pumps, and expanders. It is the 13th edition of the International Conference on Compressors and their Systems, a three-day conference organised by the Centre for Compressors Technology at City, University of London in collaboration with, among other, the MEchE, IIR, and IOR. The conference offers a platform to identify current challenges in the field and provide the essential content and direction to shape future research. The International Conference on Compressors and their Systems series began in 1999 as a result of industrial consultation and a need for academic collaboration. Initially, the conference was organised by the Fluid Machinery Group of the Institution of Mechanical Engineers (IMechE) with the support of Holroyd. From 2009, the Centre for Compressor Technology at City, University of London took over its management and the conference is now one of the main conventions, taking place biennially in the UK, becoming world-renowned for its place in industry and academia to gather and discuss a broad range of topical issues related to compressors and compression systems. This year's conference has the theme "Compressors and Expanders in Future Energy Systems” and will be of interest to researchers and engineers in industry.

Book Synopsis Numerical Simulation of Transient Performance of Viscous Micropumps by : Mohamed Omar Abdelgawad
Download or read book Numerical Simulation of Transient Performance of Viscous Micropumps written by Mohamed Omar Abdelgawad and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current trend in today's technology is the miniaturization of the mechanical components to the extent that they are about to compete with the electronics used to control their performance. In the present study, the transient performance of viscous micropumps will be investigated numerically. The viscous micropump operation depends mainly on viscous forces, and can operate in any situation where viscous forces are dominant. It consists of a cylinder placed eccentrically inside a microchannel with its axis perpendicular to the channel axis. When the cylinder rotates, a net force is transferred to the fluid due to the unequal shear stresses on the upper and lower surfaces of the cylinder, thus causing the fluid to displace. The effect of the microchannel height, rotor eccentricity, Reynolds number, and pump load on the transient performance of the viscous micropump has been studied in detail. The rotor eccentricity was determined to be the parameter that affected the transient performance of the micropump the most significantly. Multi rotor configurations were also examined and proved to enhance the micropump performance. The steady state performance was compared with the available experimental data and was found to be in a very good agreement. This work provides a foundation for future research on the subject of fluid phenomena in viscous micropumps.
