摘要
采用自适应翼型尾缘的建模方法,通过快速成型技术制作柔性叶片模型,在理论分析与数值模拟的基础上探究柔性叶片的变形规律,在水槽实验中以水轮机转子所受轴向载荷为主要研究目标,分析在低流速下叶片变形对其轴向载荷的影响。通过仿真与实验对比分析可得,柔性叶片弦向变形量随流速增加而增大,与刚性叶片对比,柔性叶片水轮机所受的轴向载荷较小,同时验证以Fluent为基础的双向流固耦合仿真方法对研究大变形柔性叶片的可行性。
A model turbine with flexible blades was designed by using adaptive airfoil trailing edge method andproduced through rapid prototyping.Deformation characteristics of the flexible blades was studied by theoretical analysisand simulation,the axial load of the turbine was measured in flume experiment and the influences of the deformation ofblades on thrust of the turbine was analyzed.Comparison between the results of simulation and experiments showed thatthe chord wise deformation of the flexible blade increased with the flow rate of the water and the thrust of the flexiblebladed turbine reduces while compared with rigid ones.The result also showed that using the method of fluid-structureinteraction analysis based on FLUENT onto the study of the problems of large deformation of flexible blades is effective.
