“…Chan et al compared two different design techniques that are conventionally used in the design of volutes for centrifugal pumps and found that the imbalanced forces due to the geometry of the volute need to be taken into consideration, especially in centrifugal pumps [7]. Zhang, Alemi, and Lu et al discussed the influence of the shape, position, and setting angle of the volute tongue on hydraulic performance and pressure pulsation of a centrifugal pump [10][11][12]. Allali and Tan et al discovered that different shapes of volute cross-sections (circular, rectangular, and trapezoidal) had different effects on flow velocity and pressure variation in volutes [13,14].…”

It is a commonly used method to design volutes for centrifugal pumps by applying statistical data. Different statistical analyses were performed by various pump technicians based on different pump samples and data-processing methodologies. When the performance parameters at the design point of a pump w given, differences in the geometrical parameters and hydraulic characteristics of the finalized volute may exist if different statistical data are applied in the volute design procedure. Two types of typical statistical data extensively used by engineers for volute design were described systematically. As the wetted perimeters of volute sections and volute inlet width are considered two key parameters that have a considerable impact on the hydraulic performance of pumps, one type of statistical data introduced a new shape of volute sections to reduce the wetted perimeter and friction area. In the second type of statistical data, the volute inlet width could be governed by designers to improve flow behavior at the volute entrance. To compare the energy-saving effects of the two types of volute design guidelines, the models of the wet parts of three pumps with different design flows and heads were established. Then, two-volute models were designed and manufactured for each impeller using two-volute statistical data, and the internal flow field of the three pumps under multiple working conditions was simulated using computational fluid dynamics (CFD) technology. The numerical results show that the head and efficiency can be improved using a shorter cross-section wet volute under the same impeller conditions. The influence of the wetted perimeters of the volute sections on the pump performances is more remarkable than that originating from the volute inlet width. The results of this research also show that the statistical data containing the above design principles should be promoted.

Mixed flow pumps driven by hydraulic motors have been widely used in drainage in recent years, especially in emergency pump trucks. Limited by the power of the truck engine, its operating efficiency is one of the key factors affecting the rescue task. In this study, an automated optimization platform was developed to improve the operating efficiency of the mixed flow pump. A three-dimensional hydraulic design, meshing, and computational fluid dynamics (CFD) were executed repeatedly by the main program. The objective function is to maximize hydraulic efficiency under design conditions. Both meridional shape and blade profiles of the impeller and diffuser were optimized at the same time. Based on the CFD results obtained by Optimal Latin Hypercube (OLH) sampling, surrogate models of the head and hydraulic efficiency were built using the Radial Basis Function (RBF) neural network. Finally, the optimal solution was obtained by the Multi- Island Genetic Algorithm (MIGA). The local energy loss was further compared with the baseline scheme using the entropy generation method. Through the regression analysis, it was found that the blade angles have the most significant influence on pump efficiency. The CFD results show that the hydraulic efficiency under design conditions increased by 5.1%. After optimization, the incidence loss and flow separation inside the pump are obviously improved. Additionally, the overall turbulent eddy dissipation and entropy generation were significantly reduced. The experimental results validate that the maximum pump efficiency increased by 4.3%. The optimization platform proposed in this study will facilitate the development of intelligent optimization of pumps.
