“…To get the best pressure distribution inside the pump, Arumugam and Sivasailam [ 21 ] tested a five‐stage vertical multistage pump at different speeds and looked into how the characteristics of pressure change in the stages of a vertical multistage pump at BEP at different rotations related to each other. Five different pump speeds were selected at BEP, and the pressure fluctuation signals were recorded and evaluated.…”

Numerous impellers are placed in line on the same shaft in a multistage centrifugal pump, comprising an impeller, diffuser, and return channel. The design of a two‐stage multistage centrifugal pump according to the specifications given in the literature was created using Creo Parametric software and validated by carrying out a numerical simulation of the first‐stage centrifugal pump by varying the number of blades and impeller speed and concluding that the pump with 7 blades and 1900 rpm rotation gives the best efficiency and head by comparing the obtained results to experimental ones. ANSYS Fluent 2022R1 was used for simulation. The optimal solutions from the first stage were used to analyze the second stage. It was observed that losses in the diffuser of the 1st stage and 2nd stage are almost the same, but head losses in the return passage of the 1st stage and 2nd stage have differences of 19.99%, 28.5%, and 23.59% for 5, 6, and 7 blades, respectively. The findings show that the multistage simulation could more accurately mirror the actual flow than the two‐stage simulation, but it also had more demanding computer configuration requirements. A two‐stage simulation is a good option for estimating pump performance because it balances computation time and numerical precision better.

The increase in power density of hydrodynamic torque converters (HTCs) leads to a sharp rise in temperature within flow channels, affecting the reliability. In order to accurately predict the thermal effect and temperature distribution characteristics of the HTC internal viscosity oil, a multi-physics computational fluid dynamics (CFD) model is proposed. A specialized test bench was established, and the macro and internal flow temperature data were obtained. HTCs with different working conditions and wheel sets were studied. The results indicate that CFD model considering energy equation can accurately predict the overall hydrodynamic performance and the flow field temperature characteristics under different rotating conditions. The prediction error of the overall temperature rise is within 4.92%, and the flow field temperature prediction error of the stator is under 14.3%. The hydraulic characteristics is improved by 6.02%. The analysis of internal flow and energy exchange characteristics indicates the thermal effects and temperature distribution mechanisms caused by energy loss in the flow field within the HTC. The study provides an effective computational model for the prediction and control of the heat generation of the HTC and enhances the depth of research on the flow mechanism of inhomogeneous flow fields caused by thermal effects.
