Abstract
In this paper, EFDC was used to analyse an area of interest for tidal current power generation and the performance of a tidal current turbine was done using CFD. Firstly, the water velocity distribution in the area of interest was obtained using EFDC and a water velocity of 2.5m/s was found. Secondly, the performance characteristics of the tidal current turbine blade was compared using experiments on a scaled down tidal turbine model and numerical analysis. The result of the numerical analysis is in good agreement with the experimental results. From the CFD analysis, the maximum efficiency obtained was 0.44 and a maximum power output of 43.18W. The experimental results showed a maximum efficiency of 0.43 and a maximum output of 42.38W. Finally, a 100kW class tidal turbine was analysed using CFD and the maximum efficiency obtained was 0.49 with a maximum power output of 119kW.
