Abstract


The purpose of this study is to develop an all in one and maintenance free power-generating facility for river, ocean or tidal flow. A swivel mile with turbine, power generator, and auxiliary systems are installed in the same axial line and under water level. This architecture can reduce the mechanical loss and increase the efficiency of electric power generation. The facility can be easily lifted up on water level for its maintenance. To realize the all in one architecture, an excellent shaft seal is required. The shaft seal can prevent ingress of water into the facility. The frictional torque of the shaft seal should also be minimized to increase the efficiency of electric power generation. A diameter of the power generator, installed into the facility, should be minimized hydrodynamic resistance from its architecture. Barnacles and algae growth onto the surface of facility reduce the generating efficiency and increase the hydrodynamic resistance. A new technology is adopted from a coating of hydrated material.

Keywords


Renewable energy; shaft seal; axial flux generator; assessment system; antifouling.
