      다국어 초록 (Multilingual Abstract)

      Seawater flow and turbine torque in a lab-scale tidal power generation system have been analyzed with CFD method. Its power generation is largely influenced by hydraulic flow characteristics of pressure variation and mechanical turbine torque in the system caused by vertical flow field including tangential rotation. Pressure drop through the turbine was gradually increased with flow rate by seawater level difference, and it depends on the turbine blade and system geometry. And curl was severely varied along the flow direction with more than about 8 times increase through the flow system. There was also turbine torque change with pressure inlet due to the water level. Those predicted results can be widely used as basic concept design data for efficient tidal power generation system development.
