The power generation efficiency of a flow driven Marine Current Turbine (MCT) depends upon the Torque (Q) induced by the flow on the turbine and the Angular velocity (ω) achieved. The greater the mass of turbine blade, the more will be the Q induced but subsequently will result in lower ω. However, on the contrary, lower mass will result in higher ω and lower Q. It is therefore necessary for any flow driven MCT to achieve the optimum balance of Q and ω so that a turbine model with maximum efficiency can be designed. In this paper, a similar study has been discussed where three different profiles by varying the radius of a horizontal axis turbine blade have been studied using numerical simulations. Emphasis has been given to obtain a blade profile which can attain an optimal combination of Q and ω to maximize the power output. The simulations have been carried out for flow velocity of 1 m/s and the average values have been reported in results.

Several different designs and prototypes of ocean current turbines have been tested over recent years. For every design test, emphasis is given to achieving an optimum power output from the flow. In this study, the performance of a Horizontal Axis Ocean Current Turbine (HAOCT) has been investigated using three-dimensional Computational Fluid Dynamics (CFD) simulations for three cases, namely, (1) a turbine without a deflector, (2) a turbine with a deflector, and (3) a turbine with a deflector operating at a higher fluid depth. The turbine design was modeled in DesignModeler software and simulations were carried out in commercial CFD software Flow-3D. The Torque Coefficient (Cm) and Power Coefficient (Cp) for the turbine have been investigated for a certain range of Tip-Speed Ratios (TSRs) in a flow velocity of 0.7 m/s. Furthermore, comparisons have been made to demonstrate the effect of the deflector on the performance of the turbine and the influence of a higher fluid pressure on the same. The results from the simulations indicate that the higher value of Cp was achieved for Case 2 as compared to the other two cases. The findings from the study indicate that the use of the deflector enhances the performance of the turbine. Furthermore, a higher fluid pressure acting on the turbine has a significant effect on its performance.
