“…The separated flow approach remains relatively reliable especially considering its popularity for pressure drop modeling. The latter is notably used for the estimation of frictional pressure drop in the straight pipes (Muzychka and Awad, 2010;Sassi et al, 2020, Arabi et al, 2021a, as well as for the estimation of the pressure drop generated by the presence of different kinds of singularity, such as the bend (Azzi et al, 2000;Azzi and Friedel, 2005;Hayashi et al, 2020), the orifice (Zeghloul et al, 2017), the multi-hole orifice (Zeghloul et al, 2018), the gate and ball valves (Zeghloul et al, 2020), the pump valve (Ma et al, 2020), the Venturi (Messilem et al, 2020) or the static mixer (Hosni et al, 2023). The liquid pressure recovery of the model of Chisholm and Sutherland (1969) is calculated using the Borda-Carnot formula based on the momentum equation.…”

The presence of a sudden expansion generates a variation of the static pressure commonly called Pressure Recovery (PR). In this paper, we made firstly an extensive literature survey to list existing gas-liquid two-phase flow pressure recovery models and to collect an experimental database. Thus, a total of 305 data was collected from 6 recent works and 18 predictive models was identified. An analysis of the different existing models was carried out firstly. Then, the predictive capability of nine existing models was assessed using the collected database. It was reported that none of the models can predict the experimental results for a large range of experimental conditions. This finding highlighted the necessity to propose a new model. The proposed predictive model was developed using the two-phase multiplier and mass quality. These two parameters were correlated using 157 data points from the collected database, while the other data was used to validate it. It was found that the proposed model gives better predictions compared to existing ones in the range of conditions and parameters of the experimental database used in this analysis.

The structure and dynamics of a reciprocating pump liquid end affect the volumetric efficiency and net positive suction head. To match the kinematics with theoretical parameters, reciprocating pump valve motion and flow visualization tests and computational fluid dynamics (CFD) analyses were performed on a wing-guided bevel discharge valve in a horizontal quintuple single-acting reciprocating pump. The valve motion test results showed that the maximum pump valve displacement and the pump valve opening and closing durations were approximately 8.3 mm, 29 ms, and 38 ms, respectively. The corresponding flow visualization test results were 11.4 mm, 9.5 ms, and 35.5 ms. The valve closing durations obtained from the valve motion and flow visualization tests are approximately twice as high as the U-Adolph prediction. The maximum displacement obtained from the valve motion test is consistent with the U-Adolph prediction. Three-dimensional CFD analyses were performed to investigate the flow states, pressure, and velocity characteristics of the discharge valve opening. Finally, the proposed method was applied to develop a new horizontal quintuple single-acting reciprocating pump with a rated flow rate of 1250 L/min and pressure of 40 MPa. This developed pump exhibited good performance and excellent reliability.

The working performance of a hydraulic system depends on the control valves, and the working performance of the control valves depends on their mechanical properties. Compared with the oil-hydraulic control valves, the water-hydraulic control valves are featured by strict sealing requirements, poor lubricity, and more complicated friction properties . In order to precisely control the valves, the fluid force and friction acting on the valve core are investigated through the methods of finite element analysis and experimental research. The results show that the realizable k-ε turbulence model with an appropriate wall roughness height could accurately reflect the state of fluid force. The fluid force increases as the valve opening and the pressure difference increase. Moreover, the friction is affected by the motion state of the valve core, and the reason is investigated. In addition, the phenomenon of mechanical properties variation is discussed, and an assumption is presented to explain the causation. This research can help understand some mechanical properties of water hydraulic valves and establish a more accurate mechanical model. Furthermore, the study also has guiding significance for controlling water hydraulic valves.
