The first one is similar to the propeller design method, the lifting line method is used for the design of the optimum circulation distribution, and the lifting surface method is then adopted for the blade geometry design. The second design procedure uses Genetic Algorithm method to design the turbine blade geometry. Hydrodynamic performances of the marine current turbine are then computed and analyzed by the potential flow boundary element method and the viscous flow RANS method. Two design examples, including a 20kw floating type current turbine, are demonstrated in the paper, and the design results show the geometries designed by both methods satisfy the design goal; however, the geometry designed by Genetic Algorithm method has a better result. It is believed that both methods are applicable for the current turbine blade designs. © Open Archives of the 16th International Symposium on Transport Phenomena and Dynamics of Rotating Machinery, ISROMAC 2016.
