摘　　要：针对弯曲流道中的水流状况改善问题,研究通过设计4种底坡坡度和设置不同长度的调整池进行优化方案设计,并结合FLUENT进行三维数值模拟计算。在流量和底坡参数相同时,弯道中水流流态恶化程度随曲率增加而严重。在进行相关工程设计时,需要避免大曲率弯道的使用。存在调整池结构时,调整池对水流流态的改善效果随弯道曲率增大而增强。研究成果可为实际工程应用中弯曲河流的设计和管理提供参考与借鉴。As the improvement of water flow conditions in curved channels becomes increasingly important,this study optimized the design scheme by designing four types of bottom slope slopes and setting adjustment ponds of different lengths,and conducted three-dimensional numerical simulation calculations in conjunction with FLUENT.When the flow rate and bottom slope parameters are the same,the degree of deterioration of the flow pattern in the bend becomes more severe as the curvature increases.When carrying out relevant engineering design,it is necessary to avoid the use of large curvature curves.The existence of an adjustment pool structure enhances the improvement effect of the adjustment pool on the flow pattern as the curvature of the bend increases.The research results of this study have important guiding significance for the design and management of curved rivers in practical engineering applications.
