Centrifugal pumps are frequently utilized in general machinery, but they have issues with low efficiency, unstable operation, and high-power consumption actual engineering, making performance improvements necessary. In this paper, the particle swarm algorithm is to find optimal solution among Pareto front solutions obtain most suitable impeller for centrifugal pump lowest entropy generation hig...
The Gyro centrifugal pump, developed as a totally implantable artificial heart, was designed with a free impeller in which the rotational shaft (male bearing) of the impeller was completely separated from the female bearing. For this type of pump, it is very important to keep the proper magnet balance (impeller-magnet and actuator-magnet balance) to prevent thrombus formation or bearing wear. W...
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 soft...
the non-uniformity factor is used for correction of the formulas obtained from the one-dimentional fluid flow method in a centrifugal impeller pump. the variations of radial velocity at the outlet of five centrifugal impellers with the specific speed of about ns =50 are calculated at design point by using two-dimentional potentional flow method for an invisid fluid. on the other hand~ the varia...
The inducer is often used to prevent cavitation in a centrifugal pump. However, it may lead deterioration of the performance pump when poorly matched with impeller. Numerical simulations are employed study effects matching, specifically, axial space and circumferential deflection between impeller, on performance. results show that destroys rotational symmetry velocity distribution at inlet resu...
