| Summary: | In order to improve the fine optimization technology of flow measurement facilities in irrigation areas, the hydraulic characteristics optimization system of an airfoil pillar-shaped flume is constructed. The optimization system integrates three modules of airfoil shape reconstruction by Hicks–Henne function, CFD numerical simulation calculation, and NSGA-II algorithm. It can efficiently find the shape design variable value that makes the hydraulic characteristics optimal. An example of the airfoil pillar-shaped flume in a rectangular channel at 30 L/s of discharge rate is given, and the specific optimization design concept of backwater height and head loss is presented. The results show that the backwater height is reduced by 9.49% compared with the prototype, and the head loss is reduced by 8.10% compared with the prototype, proving the feasibility of the optimization system. It can provide a theoretical reference for the optimization of hydraulic characteristics of similar measuring flumes.
