摘　　要：研究水平轴水轮机的尾流场,在循环水槽中开展试验工作,采用ADV测量流速特性。利用计算流体力学技术进行数值模型研究,结合致动盘理论将水轮机进行简化,与试验结果进行对比分析,验证此方法的可行性。研究尾流场中速度和湍动能的变化规律,发现衰减系数在8D之后趋于一致,湍动能最大值出现在3D附近等现象。The wake of the horizontal axis turbine was studied in this paper,and the test work was carried out in the circulating water flume,the flow velocity characteristics were measured by ADV.The numerical model research was carried out by using technology of computational fluid dynamics,the actuator disc theory was used to simplify the turbine.The experimental results were compared with numerical results,the feasibility of this method was verified.The characteristics of velocity and turbulent kinetic energy of wake was studied.The deficit coefficient tends to be same after 8D and the maximum value of turbulent kinetic energy appears around 3D was found.
