“…In 1988, Max Gurth developed the second-generation disc pump, which greatly improved the energy efficiency and expanded application scalability [74][75][76]. Due to the development gap in the initial stage, the research on the flow characteristics and optimization of the second-generation disc pump was mainly carried out in recent years [77][78][79][80].…”

Disc pumps have obvious advantages in dealing with difficult-to-pump media. Energy efficiency and sustainable energy management are important topics with regard to reducing costs and promoting carbon neutrality. Though the concept of the disc pump was proposed in the 1850s, development was slow and limited by its initial model. However, with the development of industries such as petrochemicals and food, the efficient pumping of difficult-to-pump media is much needed, but facing challenges. Therefore, research on energy-efficient disc pumps is particularly important moving forward. In this paper, the available information from the open literature about the research and development of the disc pump will be thoroughly reviewed. It focuses on the historical development, energy efficiency and physical model application of the disc pump. The review ends with a proposal for the direction of future development, and in this aspect, it is proposed that the energy efficiency prediction model based on velocity slip theory, the energy management system based on multi-scenarios and the design method based on energy conversion theory are important. The latest achievements in energy conversion are given. This review also provides a new perspective for the development of energy-efficient disc pumps.

“…Through the RRF/MRF approaches different kind of pumps were studied. In particular, centrifugal pumps were simulated in [77][78][79][80][81], an axial-flow pump was studied in [82], and a vortex pump working with highly viscous liquid flow condition was simulated in [83]. In addition, also the study of a Francis turbine was performed through these approaches [84].…”

“…Therefore, most of the work using the RRF/MRF approaches has been conducted through commercial software. More specifically, ANSYS FLUENT was used in nine works [23,[25][26][27][28]30,76,78,83] and ANSYS CFX was exploited in 8 papers [24,72,73,77,80,81].

The lubrication of the mechanical components reduces friction, and increases the efficiency and the reliability. However, the interaction of moving components with the lubricant leads to power losses due to viscous and inertial effects. Nowadays, the study of lubricant behavior can be carried out through computational fluid dynamics (CFD) simulations. Nevertheless, the modeling of the computational domain within complex mechanical systems (e.g., ordinary, planetary and cycloidal gearboxes, roller bearings, and pumps) requires the exploitation of specific CFD techniques. In the last decades, many mesh-based or meshless approaches have been developed to deal with the complex management of the topological changes of the computational domain or the modeling of complex kinematics. This paper aims to collect and to classify the scientific literature where these approaches have been exploited for the study of lubricated mechanical systems. The goal of this research is to shed a light on the current state of the art in performing CFD analysis of these systems. Moreover, the objective of this study is to stress the limits and the capabilities of the main CFD techniques applied in this field of research. Results show the main differences in terms of accuracy achievable and the level of complexity that can be managed with the different CFD approaches.

“…Zhou et al [15] used numerical calculation method to analyze the effects of space diffuser, and they found the seven vanes matched the impeller very well. In terms of viscosity effects, Li and Zhang [16] studied the effect of viscosity on the hydraulic performance and flow characteristics of a vortex pump. Beyond that, Li [17] studied the effect of viscosity on the performance of the pump as turbine.…”

In order to reveal the influence of medium viscosity on flow characteristics in rotary lobe pump, the flow of five media with different viscosities, ranging from 1 (cst) to 110 (cst) has been studied in this paper. Based on the dynamic mesh model and the deformation technology of local grid reconstruction, the effects of viscosity, gap structure and speed on flow rate and pressure were investigated by transient numerical simulation, which were also verified by experiments. The results show that the viscosity has a significant influence on the performance of rotary lobe pump. With the increase in viscosity, the flow of fluid in rotor cavity tends to be steady. And the viscosity force could hinder the leakage flow of the medium in rotor cavity to some extent. The change in viscosity of the fluid medium would affect its outlet flow rate, and the outlet flow rate of 110 (cst) medium is 40% higher than that of the 1 (cst) medium. As the rotational speed is reduced from 400 (r/min) to 100 (r/ min), the outlet flow rate decreases by 95% at 11 (cst) and by 80% at 72 (cst). Additionally, compared with the fixed gap structure, the gradient gap structure can effectively optimize the flow pulsation in the low-viscosity fluid, which reduces the pressure fluctuation by more than 30%.
