Abstract
In this study, a Francis turbine with specific speed of 130 m-kW was designed on the basis of the port area and loss analysis. The meridional shape of the runner was designed focusing mainly on the combination of the guide vane loss analysis and experience. The runner blade inlet and outlet angles were designed by calculation of Euler’s head, while the port area of blade was modified by keeping constant angles of the blade at inlet and outlet. The results show that the effect of the port area of runner blade on the flow exit angle from runner passage is significant. A correct flow exit angle reduces the energy loss at the draft tube, thereby improving the efficiency of the turbine. The best efficiency of 92.6% is achieved by this method, which is also similar to the design conditions by the one dimension loss analysis.

Summary
There is an increasing demand for renewable energy for sustainable development to solve the coming energy crisis. The necessity of the use of renewable energy as one of the clean and sustainable natural energy resources has become high. Francis turbines are applicable to a wide range of head and specific speed values. Their wide range of applicability and easier structural design makes Francis turbines more advantageous than other hydraulic turbines. A Francis turbine runner blade with good performance by the one dimensional hydraulic design method can be designed effectively and successfully. Korea relies on foreign products, and the technology for local manufacture was limited until 2010 [1]. Korea is in the process of developing its hydropower technology
