摘要
借助计算流体力学(CFD)方法研究潮流能水平轴水轮机水动力学性能,选择合适的湍流模型至关重要。为此,本文采用计算流体力学软件Fluent,将Spalart-Allmaras湍流模型、标准k-ε湍流模型、RNGk-ε湍流模型、标准k-ω湍流模型和SSTk-ω湍流模型分别应用到水平轴水轮机数值模拟当中。对数值模拟结果进行分析比较,并与模型试验数据进行对比,得出应用SSTk-ω湍流模型可以更好的模拟潮流能水平轴水轮机的水动力学性能。
A proper turbulence model is necessary to simulate the hydrodynamic performance of horizontal axis tidal current turbines with the aid of computational fluid dynamics (CFD) method. Spalart-Allmaras model,standard κ-ε model,RNG κ-ε model, standard κ-ε model and SST κ-ε model were used to simulate the hydrodynamic performance of a horizontal axis tidal current turbine by using software Fluent. The results of numerical simulation were analyzed and compared with the experimental results. It is showed that the calculations rising SST κ-ε model are better than other models in simulating the hydrodynamic performance of horizontal axis tidal current turbines.
