Abstract: As a critical part of tidal current energy conversion device, the turbine plays an important role to
determine whether the hydrodynamic performance is well or not. By means of the design and analysis methods fo
wind turbine blade, the turbine blades of an axial-flow tidal current turbine newly developed by the author have
been optimized. The results attributing to numerical simulation show that it has nice conversion efficiency when the
turbine is set to revolve at speed 100 r/min. Otherwise, it has been found that the polygonal duct with 15? attacked
angle has good hydrodynamic performances and can greatly improve the efficient of the tidal current turbine system
It has been Testified that in the case of same conditions. the output conversion power of tidal current turbine with
duct is about 30%o larger than that that concerning the case without it
