摘　　要：物理模型试验是研究导流洞水力特性最普遍的方法,但存在缩尺效应等缺点。为了探索采用数值模拟的方法来研究导流洞水力特性的可行性,用Fluent商用计算软件,对某工程的单条导流洞进行了数值计算,得出了压强沿程分布、流速和流态等水力特性,选取典型断面的计算结果与模型试验结果进行对比,两者符合较好,验证了数值计算方法的可行性。数值计算方法可作为模型试验的辅助手段,并为Fluent软件在导流洞体型优化设计中的应用提供了参考依据。The most common approach to studying the hydraulic characteristics of the diversion tunnel is the model test, which has some shortcomings such as scale effect. The universal software Fluent is applied to study the hydraulic characteristics of diversion tunnel. The distribution of pressure along the flow direction, velocity, the flow condition and so on is calculated. Compared with computation results and the model test results of several typical sections, the results are in good agreement with the model test, which verifies the feasibility of numerical calculation method. The numerical calculation method can be used as the auxiliary methods of model tests and provide a reference for Fluent software in the shape optimization design of the diversion tunnel.
