The invention provides a method and device for measuring flow in a curved channel. Wherein, the method includes: determining the flow velocity distribution model of the curved channel; according to the velocity distribution model of the curved channel, the flow velocity partition of the curved channel and the characteristics of the dividing line, determining the representative point position of the normal average flow velocity of the section of the curved channel; The established three-line-polygon division method divides the cross-sectional area of the curved channel according to the position of the representative point of the normal average velocity, and obtains the flow information of the curved channel based on the velocity area method. By adopting the method for measuring flow in a curved channel disclosed by the invention, the flow measuring process can be simplified under different hydraulic conditions, and the accuracy and efficiency of flow measurement in a curved channel can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of computer applications, in particular to a method and device for measuring flow in a curved channel. In addition, it also relates to an electronic device and a non-transitory computer-readable storage medium. Background technique [0002] Measuring open channel flow is an important issue in hydraulic engineering. The most commonly used section type of open channel in irrigation areas is the trapezoidal section, which has the outstanding advantages of regular section, stable slope, low construction technical difficulty and strong applicability. However, the trapezoidal section is usually weak in anti-heaving frost ability, while the curved channel section has superior hydraulic conditions such as large flow rate, strong sediment transport capacity, and remarkable anti-seepage effect. In particular, as various curved channel sections (such as circular, U-shaped, parabolic, etc.) research hotspot. In conv...
