FEASIBILITY VERIFICATION FOR TIDAL CURRENT POWER GENERATION USING BRIDGE PIER BY CFD FOR TIDAL CURRENT INCLUDING TURBULENCE

Abstract

 In this research, we perform numerical analysis the tidal current using CFD targeting the Ohshima Ohashi bridge fourth bridge piers over Obatake Seto strait. Based on the numerical analysis results, the tidal current distribution and the turbulence intensity distribution near the bridge piers were analyzed in detail. In consideration of the influence of the tidal current and turbulent intensity near the bridge piers on the power generation device, the optimum installation position of the power generation device was selected.As a result, it was predicted that the total amount of power generated by the Oshima bridge No. 4 pier would be approximately 323.8 MWh per year, indicating the feasibility of tidal power generation in this area.
