“…Because the working mechanism of a vortex pump leads to a complex flow of the medium in the channel, more vortexes are formed during the flow process, resulting in a large amount of energy loss. So, the working efficiency of vortex pumps is low, usually less than 50% [4,5]. The efficiency characteristics of a vortex pump are characterized by a steep drop under the condition of a large flow rate.…”

Magnetic vortex pumps are characterized by their high performance and zero leakage, and in recent years, they have been applied for the transportation of antifreeze coolant in varying-temperature environments. This paper combines Computational Fluid Dynamics (CFD) with experimental verification to study the external and internal flow characteristics of magnetic vortex pumps when transporting working fluid at different temperatures, considering radial clearance flow. The results indicate that as the temperature of the medium increases, both the pump head and efficiency improve. Specifically, under the design flow rate condition, the pump head increases by 16.7% when transporting a medium at 90 °C compared to ambient-temperature conditions. Conversely, the pump head is only 16.8% of that observed under ambient-temperature conditions when transporting a medium at −30 °C. Analysis of the internal flow field reveals that the changes in pump hydraulic performance at different working fluid temperatures are primarily due to variations in the vorticity of the internal flow field.

“…Sun et al (2021) investigated deformational and vibration laws of axial flow compressor blade with different materials with the fluid-structure coupling principle. Danilishin et al (2020), Kumar et al (2022) and Kumar and Wurm (2015) applied the pressure load and temperature load calculated by CFD to the coupling surface of centrifugal impeller blades via a one-way coupling method. Moreover, the authors analyzed the influence of pressure loads, fluid temperature and centrifugal force on impeller deformation and stress.…”

Purpose There are three purposes in this paper: to verify the importance of bi-directional fluid-structure interaction algorithm for centrifugal impeller designs; to study the relationship between the flow inside the impeller and the vibration of the blade; study the influence of material properties on flow field and vibration of centrifugal blades. Design/methodology/approach First, a bi-directional fluid-structure coupling finite element numerical model of the supersonic semi-open centrifugal impeller is established based on the Workbench platform. Then, the calculation results of impeller polytropic efficiency and stage total pressure ratio are compared with the experimental results from the available literature. Finally, the flow field and vibrational characteristics of 17-4PH (PHB), aluminum alloy (AAL) and carbon fiber-reinforced plastic (CFP) blades are compared under different operating conditions. Findings The results show that the flow fields performance and blade vibration influence each other. The flow fields performance and vibration resistance of CFP blades are higher than those of 17-4PH (PHB) and aluminum alloy (AAL) blades. At the design speed, compared with the PHB blades and AAL blades, the CFP blades deformation is reduced by 34.5% and 9%, the stress is reduced by 69.6% and 20% and the impeller pressure ratio is increased by 0.8% and 0.14%, respectively. Originality/value The importance of fluid-structure interaction to the aerodynamic and structural design of centrifugal impeller is revealed, and the superiority over composite materials in the application of centrifugal impeller is verified.

The mud pump is an important power component of petroleum drilling. The crankshaft, as an important part of the mud pump, requires optimization of the crankshaft structure in order to improve the efficiency of the mud pump. First analyze the workload of the crankshaft, and obtain the stress point and load size of the crankshaft work. Through the finite element simulation, the corner of the crank rotation and the maximum deformation of the crankshaft and the maximum stress is obtained. Combining the production process to open the hole, use the non -linear regression model to establish the relationship between the crankshaft structure optimization target and the opening diameter of the opening, and use multiple target optimization methods to find the optimal variable. The maximum stress, maximum variable volume, and the total mass optimization effect of the crankshaft is obvious, reducing product costs.
