Abstract
Flow characteristics of a fish-type current power generation system have been investigated by the use of a volumetric PTV.

Three types of the turbine blades have been tested under the current speed 1.35knot, 1.5knot and 2knot. The width of the blade installed around the body is 50mm. The load test has been carried out under the same flow conditions.

All flow features have been investigated when the blade have come to the same rotating angle position using a position sensor. Among the models it has been verified that the S65 showed the highest voltage generations. For the case of S65 turbine model, the deficit of the velocity magnitude in the wake region seems to contribute the transfer of moments from the current fluids to the turbine blade.

It is estimated that the power efficiencies of the present turbine blades are ranged from 10% to 20% at most.
