“…The centrifugal pump used for the experiment method has a power of 746 W. The utilization of centrifugal pumps in this research due to the percentage of centrifugal pump applications in the industrial sector has reached 75%. Moreover, the centrifugal pump also has stable specifications based on pressure head, centrifugal pump efficiency, NPSH, and fluid flow rate [20]. The experiment method scheme explains that the fluid flow from a storage tank will pass through a centrifugal pump, which has two impeller models (as seen in Fig.…”

This research analyzes the impeller design performance that has been modified based on previous impeller designs. The previous impeller design used high engine power consumption due to the total head, so the modification of the impeller design is expected to reduce the engine power consumption. The existing design and the modified impeller design with the addition of the junction disc plate are used by this research. This research used experiment methods and theoretical methods to compare both of impeller design performances. The experiment method measures total head, fluid capacity, engine speed, and engine power consumption. The theoretical method analyzes actual fluid velocity, specific velocity, total suction head, NPSH, and pump efficiency. The results showed that the fluid flow rate was able to increase the efficiency of the centrifugal pump by 2.8%. The conclusion explains that the addition of a junction disc plate produces energy from a steady fluid flow rate to reduce the engine power consumption and escalation of pump efficiency.

“…an intermediate approach between URANS simulations and Direct Numerical Simulation DNS, which aims to describe both the large-scale and small-scale turbulent flow structures. Although the URANS models perform well in calculating the flow confined by walls, it should still be noted that the use of such models is important in solving complex multi-physics problems of turbomachinery, such as thermal calculations in zones of non-stationary mixing of flows at different temperatures, when simulating vortex cavitation, which is caused by a non-stationary turbulent pressure field, modeling acoustics in hydraulic systems when turbulence creates noise sources, etc [8][9][10][11][12][13][14]. These models include Large Eddy Simulation (LES), a model that decomposes the flow into large-scale vortex structures and models the small-scale turbulent eddies and its hybrids with RANS models.…”

This paper explores the optimal simulation settings required by the optimization process of centrifugal canned motor pump parts using the CH 6,3/32-2,2-2 pump as an example. The optimization of centrifugal pump parts is particularly important in order to increase pump characteristics: pump efficiency, net positive suction head, as well as other optimization criteria. The optimal conditions to obtain a geometric model and optimal mesh properties, initial and boundary conditions, solver settings were investigated. The mathematical models used in the simulation were also presented. In conclusion, there have been revealed optimal simulation settings.

The acoustic distribution characteristics inside centrifugal pump impeller under different blade outlet angles are explored based on the Powell vortex sound theory. It is shown that the increase in the blade outlet angle narrows the fluctuation ranges of the acoustic source and acoustic pressure perturbation at the impeller outlet far away from the tongue, while extends those near the tongue. The total acoustic source intensity and total acoustic pressure level at the impeller outlet far away from the tongue decrease by 1.23% and 1.17%, respectively, while those near the tongue increase by 0.64% and 0.94% when the angle increases from 15° to 35°, respectively. Additionally, under different blade outlet angles, the total acoustic source intensity and total acoustic pressure level on the streamline far away from the tongue increase rapidly first, then increase slowly from inlet to outlet of the impeller. On the streamline near the tongue, a mutation of total acoustic source intensity and total acoustic pressure level appears near the impeller outlet, and the mutation range moves towards the middle section of the impeller with increasing blade outlet angle and rotational speed. In addition, the A-weighted average acoustic source intensity level and A-weighted average acoustic pressure level increase by 0.4% and 1.22% when the angle increases from 15° to 35°, respectively. The study reveals the rotor–stator interaction intensity evolution characteristics, and provides a reference for the optimization design of centrifugal pumps.
