将紊流两方程k-ε模型应用于明流泄洪洞的流场分析，采用体坐标变换处理复杂的边界及模拟自由水面，获得了流速、紊动能、耗散率、压力等参数的分布。与有关实测资料对比分析，结果令人满意。
The k-ε turbulence model was applied to the flow field analysis of the Mingliu flood discharge tunnel. The complex boundary and the free water surface were simulated using volumetric coordinate transformation. The distribution of the parameters such as flow velocity, turbulence energy, dissipation rate and pressure were obtained. Compared with the measured data, the result is satisfactory.
