In this paper, 1-D design of axial flow hydraulic turbine including runner blades, spiral casing with distributors(guide vanes and stay vane), and draft tube was conducted and then 3-D flow analysis was carried out using CFX-12.1. The results of 3 runners showed that with an increase in the number of blades, the flow rate and the power of the turbine system increased. On the other hand, the runner loss was not directly connected with the number of blades. As a result, proper blade number could be selected and more than 100㎾ small hydraulic turbine could be designed.
