摘要
为推进海洋可再生能源的发展与利用,提高海洋能捕获机构的效率,以水平轴式海洋能捕获机构为对象,结合计算流体力学原理,利用RNG k-ε来模拟机构流场的湍流流动,给出了机构有限元网格划分方式,通过计算机仿真模拟分析优化机构叶片布置数量。在此基础上,以不同来流攻角方向对机构叶片特性进行分析,分析了不同攻角情况下的流场状态,给出了攻角变化范围,并讨论给出了分析结果。
To promote the development of renewable ocean energy sources and to utilization and improve the efficiency of capture mechanism,the number of turbines and composition of body mechanics is studied based on the simulation of the turbulence flow organization with computational fluid dynamics( CFD) via RNG K-ε,and the finite element meshing method of the mechanism is presented. Based on the above-mentioned dicussion,the turbine characteristics are studied under different angles of attack and the state of the flow field is studied; finally the best angle of attack range is presented.
