中文摘要：

随着化石能源不断枯竭和环保要求的不断提高,世界各国对海流能的开发利用愈加重视,各种利用海流流动动能发电的技术得到了快速发展。通过对国内外海流能发电状况的调研,在总结叶片翼型的发展状况基础上,选取合适的翼型采用遗传算法对该翼型的几何特征进行了分析和优化,得到了一种新的具有较小阻力的海流发电机翼型,与试验数据比较证明该方法正确性,具有实用价值。

英文摘要：

Fossil resource depletion is predictable and the requirements of environmental protection become stringent, all the countries are paying more and more attention to marine current energy extraction Different kinds of Marine Current Turbines absorbing the marine hydrokinetic energy emerged. After investigation of the Marine Current Turbine development abroad and domestic, the theoretical development of hydrofoil used for Marine Current Turbine is concluded in this paper. It also evaluates hydrodynamic behavior of chosen hydrofoil and obtaines a better new one with minimum drag through an optimization process. The results are compared with test data and the process is proved to be efficient.
