中文摘要：
利用Fluent软件,采用VOF法和k-ε紊流模型对矩形无吼段量水槽水力特征进行三维数值模拟,得到沿程水面线及其流速分布规律,并将模拟结果与实测结果以及公式计算结果进行对比验证,结果显示,模拟结果与二者的吻合度较好。在确定模拟准确性的前提下,对其水力特性进行分析,为矩形无喉段量水槽的设计和优化提供一定依据。
英文摘要：
The hydraulic characteristics of rectangular throatless measuring-flume is simulated by the volume of fluid（VOF） method and k-ε turbulence model,the rule of water-surface line and velocity distribution is obtained.Then the results of simulation,experiment and formula calculation are compared.The results show that the above data coincide well.The hydraulic characteristics are analyzed,and serve as a reference for structure design and parameter optimization of measuring-flume.
