Abstract
In this study, actual material manufactured and used actually in the corporation was embodied by CATIA V5, results of flow characteristics that were obtained from numerical analysis on pressure distribution and velocity distribution from inlet port to outlet port of centrifugal pump, flow phenomenon of water cut, and path of particle were compared with actual performance curve of centrifugal pump through commercial program, ADINA 9.0 and reliability of flow characteristics numerical analysis was confirmed. In addition, the comparison of numerical analysis and performance curve of centrifugal pump, outlet pressure head is nearly be a unit. In this study, biased phenomenon of impeller outlet pressure was confirmed and it prepared an opportunity to improve the phenomenon. And it should be much helpful to improve pump performance if analyzing flow characteristics of centrifugal pump used in industrial field for various purposes, grasping the reasons making an effect on pump performance and improving them.
