Among the ocean energy resources, wave power takes a growing interest because of its enormous amount of potential energy in the world. However, suitable turbine type is not normalized yet because of relatively low efficiency of the turbine systems. The purpose of this study is to determine suitable shape of front guide nozzle angle of a direct drive turbine for wave power converter.

A lot of countries are trying for small hydro power utilization that is clean source of energy as environmental problem is weighed and necessity of renewable energy utilization becomes serious. Try in technical development continuously in domestic and develops some hydro turbine and improved a technology but in the case of water-turbine generator development, our country that is point of decimal power development system, season, because different flux change is big, need development of suitable hydro turbine there. Localization and standardization of hydro turbine become important problem. So, easy of standardization by simple structure and flux fluctuation of cross-flow hydro turbine is point that application is possible in large place act by big advantage in application of sale through illegal channels hydro turbine. The purpose of this study is the variation of runner angles to improve the performance. Optimization of the turbine structure has been made by the analysis of the turbine performance with the variation of the runner angle using a commercial CFD code. The results show that inlet and outlet runner angles give considerable effect on the performance of the turbine.
