摘要

本文利用ANSYs Fluent软件对阿基米德螺杆式水轮机的六自由度(6-DoF)方法和滑动网格方法进行了流体动力学仿真比较。在文献实验数据的基础上，比较了功率系数()值与叶顶速比()的数值曲线。因此，将该数值作为数值与实验数据的比较基准参数，采用六自由度法和滑动网格法得到的误差分别为13%和40%。两种方法都可以模拟转子的旋转，虽然6自由度方法在涡轮性能预测上更准确，但与滑动网格方法相比，消耗的计算资源更高，可以在负担得起的时间内获得计算解。

Performance simulation of water turbines by using 6-DoF UDF and sliding mesh methods

In this work, a comparison between the six degrees of freedom (6-DoF) method and the sliding mesh approach in computational fluid dynamics simulations of an Archimedes screw turbine for hydrokinetic applications was performed using ANSYs Fluent software. The numerical curves obtained by representing the power coefficient () values versus the tip speed ratio ( or ) were compared based on the experimental data available in the literature. Therefore, by considering the values as the comparison benchmark parameter between the numerical and experimental data, the error obtained when using the 6-DoF method and the sliding mesh approach was 13% and 40%, respectively. Both methods allowed the simulation of the rotor rotation, although the 6-DoF method was more accurate in the prediction of the turbine performance, higher computational resources were consumed in comparison with the sliding mesh method, which allows to obtain a computational solution in affordable times.
