“…When fluid flows through a curved path, centrifugal forces generate pressure and velocity differences across the path, as documented in previous studies [2,3]. This phenomenon carries valuable information about physical quantities, making it essential for detailed observation in both simulations and experiments, as demonstrated by Kumar et al, [4] and Cao et al, [5]. Consequently, constructing a suitable computational domain becomes essential to accurately capture and represent this information.…”

Mesh generation is critical for obtaining accurate and detailed solutions to mesh-based numerical problems, particularly when capturing specific information within a designated area of the domain. While structured meshes offer consistency, their uniform resolution limits their ability to achieve this. Mesh stretching offers a solution by introducing non-uniform element sizes based on an analytical relationship while preserving the original mesh structure. The objective of this study is to create a hybrid mesh model that leverages the strengths of both structured and stretched meshes. A 2D rectangle with elbow edges serves as the domain. To address the requirements of CFD applications, the domain is refined by increasing element density near the boundaries and corners. Skewness, aspect ratio, and element quality are then assessed to determine the overall mesh quality. The results demonstrate that stretching the structured mesh produced a mesh with quality that meets CFD domain standards.

“…The majority of industrial hydraulic installations are sporadically innovated based on the current production process requirements or changes in the production portfolios of undertakings. A similar situation exists with regard to new installations, which often need adjustments, after only a few years, to the current requirements regarding the demand, operation cost-efficiency and effectivity, as well as the environmental impact [1][2][3][4][5][6].…”

In this article, an analytical solution to a hydraulic network with a wide range of pipe lengths (up to 10 km) is proposed. The Finite-Difference Time-Domain (FDTD) method was applied with the aim of creating a regulation model for controlling both the flow rate of water from one of the two sources and the discharge pressure in the system. The system inertia requires an understanding of boundary conditions in the operation of pipeline networks, which must be known in order to regulate the required parameters with only minor deviations. The proposed model was compared to experimental data, while the mean absolute deviations in the individual system branches ranged from 1 to 5.19%. The created regulation model was subsequently tested by applying linear, sine and stochastic changes in the output load, while the ability to control the discharge pressure and the selected water flow rate was analysed. The effect of coefficient ε, which multiplies the effect of the difference between the measured and the predicted value of the discharge pressure on the boundary conditions of the discharge pressure in the system, was analysed in this paper. With the use of the proposed unsteady simulation of the fluid flow in the hydraulic system arranged in parallel and in series, the maximum deviation of the regulated pressure was 1.2% and the maximum deviation of the regulated flow rate was 5.3%.

“…Compared with experiments, numerical simulations are very suitable for analyzing the flow characteristics of flow channels because of their low cost, short cycle time, and the ability to monitor specific flow conditions. Shivam Kumar et al [25] has studied numerical simulation of the flow of fluid in a pipe at different velocities led to the conclusion that the main reason affecting the head loss in a straight pipe is frictional resistance and the main reason affecting the head loss at an elbow is the centrifugal force of the fluid. Wang Liwei et al [26] used the RNG k-ε model, Realizable k-ε model and Reynolds stress model to conduct computational fluid dynamics analysis of the bend with a 90° turning angle, and found that the Reynolds stress model can better predict the secondary flow phenomenon in the bend, which brings about the pressure loss.…”

Selective laser melting has the potential to be applied into hydraulic pipelines manufacturing because it can realize the forming of flow channels with arbitrary direction and curvature. Due to the stacking of layers, selective laser melting still has many limitations while processing complex flow channels. In particular, the manufacturing of overhanging structures with circular cross sections needs to use internal supports to prevent surface collapse, which is challenging to be removed. Therefore, it is necessary to optimize the flow channel with a self-supporting ability, then systematically discussing its forming quality with the influence on fluid dynamics to compromise. In this paper, a simplified multi-channel structure with 1 inlet and 4 outlets is extracted from a hydraulic valve block of an aero-engine system, and the cross-section of its branch channel is re-designed to guarantee its self-supporting ability based on additive manufacturing optimization strategy. Numerical simulation was used to analyze the influence of different shape sections on the pressure loss and mass flow rate of multi-channel structure. The results show that the pressure loss and outlet flow of the 45° rhombus + ellipse section are the closest to the circular area. According to the maximum internal deformation of the three outlets, the 65° rhombus section has the better forming quality and the non-circular section is not the worst.
