“…Orthogonal optimization was performed along with FEM analysis for the pumping unit, and the results showed that Taguchi's method was an efficient and effective approach. Zhao et al 20 proposed a novel approach to optimize a doublechannel pump based on the combined use of orthogonal testing and CFD. An orthogonal table was implemented to obtain the optimized design, and CFD analyses and experiments were conducted to evaluate the optimized design.…”

Tubular pumps are widely used in irrigation and water conveyance projects. However, the operating head of most of these pumps is low, and only a few studies have focused on the design of an efficient tubular pump with a head more than 5 m, which is common in long-distance water supply projects. This work aims to improve the operating head and efficiency of tubular pumps while maintaining a low shaft power. The multi-objective orthogonal optimization method was used to determine the critical parameters of the tubular pump, i.e., blade number, airfoil, blade thickness and guide vane distance, and nine design schemes were selected. Next, by using computational fluid dynamics (CFD), a 3D model of the tubular pumps under different schemes was established, and the results were compared. Subsequently, the range method and weighted matrix method were utilized to find the optimized scheme. In addition, an experimental investigation was performed to verify the simulation and the performance of the designed tubular pump. The results indicated that the optimized scheme improved the operating head to 6.9 m with higher efficiency of 84.2% and a lower shaft power of 27.7 kW. The modeling results were in agreement with the experimental measurements, and the designed tubular pump had a wide range of high-efficiency zones.

“…According to the orthogonal method, the parameters are arranged to meet the principle of orthogonality, and hence the number of test cases can be reduced to achieve efficient optimization. Many investigations [20][21][22][23][24] have validated the reliability of the orthogonal method on the optimization of hydraulic machinery.…”

The hydraulic design method of controllable blade angle for rotodynamic multiphase pump with impeller and diffuser is proposed. The distribution of blade angle along the meridional streamline is governed by the normalized fourth-order and first-order polynomial function for impeller and diffuser, respectively. The orthogonal optimization method with five factors and four levels is employed by numerical simulation to optimize the geometry parameters, including the shroud angle at the leading and trailing edge β Is0 , β Is1 , the blade difference at inlet ∆β I0 , and the coefficients at hub and shroud k h , k s. According to orthogonal analysis, the influence of each factor on pressure rise is estimated, and the optimization values of for those parameters are determined. The pressure rise of optimization multiphase pump is increased by 12.8 kPa in comparison of the base pump. Results show that the distributions of gas volume fraction (GVF) and the pressure become more uniform after optimization, which improves the transporting performance of the multiphase pump.

High voltage power was used to produce jet in electrospinning. It was very difficult to study electrospinning jets by experiment, because they have high-speed and complex movements in the high-voltage electrostatic field, and the diameter of jet was very small. In this study, the software of finite element analysis was used to simulate the formation process of a stable jet in electrospinning. The numerical simulation results indicated that the diameter of a stable jet decreased as well as the velocity of a stable jet increased with the increasing of drafting force when the solution flow rate was constant. At last, an experiment about a stable jet diameter has been carried out. The different conductivities spinning solution by adding different content lithium chloride into polyvinyl alcohol solution have been prepared. They could lead to different electric force for a stable jet in electrospinning. We used glass slide to intercept the stable jet to test the diameter of jet. The experiment results showed that the diameter of a stable jet decreased with the electric force increased. The experiment results were in good agreement with numerical simulation of a stable jet in electrospinning.
