为了研究不同湍流模型在建立数值水槽中的适用性，选用计算流体力学软件，采用S-A、标准的k-着及RNG k-着等8种不同的湍流模型对水槽中的波浪进行了数值模拟，通过对比得到：RNG k-着模型不仅具有较高的精度，而且又节省计算资源，较其它模型更具优势。

In order to evaluate the applicability of turbulence models in building numerical wave flume, computational fluid dynamic (CFD) software was used to simulate the wave by eight different turbulent models include:S-A, Standard k-ε and RNG k-ε model and so on. Comparison of the computed results showed that the RNG k-ε model not only had high precision but also saved the computing resources,so it had more advantages than the other models.
