Influence of blade inlet angle on the performance of a single blade centrifugal pump

Single blade centrifugal pump is suitable for transporting sewage water with large obstacles in diameter, which required to achieve high performance. The inlet angle a parameter that affects the performance of single pump. However, selection frequently based on experiences and demonstrates certain arbitrariness. Therefore, six impellers different angles are designed using ANSYS Bladegen NX software. These categorized into Groups 1 2. Group1/Group2 increases/decreases from front shroud rear one, respectively. Subsequently, numerical simulation carried out investigate effect has more obvious influence head, efficiency, shaft power Group than those lowest pressure negative one 1. Moreover, an optimum improves In addition, alternating load small blades present results helpful designing improving its
