This paper is presented to the hydrodynamic performance of horizontal axis tidal stream turbine (HATST) with different blade geometries. The Reynolds-averaged Navier-Stokes (RANS) equations solver of the Star-CCM+ software is employed with a realizable k-ε turbulent model. The turbine has three blades and different blade NACA sections. The numerical results of pressure distribution, power and thrust coefficients (CP and CT) are presented and discussed at various tip speed ratios (TSR). It is found that the maximum power coefficients are obtained around 0.37 to 0.41 at TSR between 4 and 5. The results of thrust coefficients are found that 6418 is more than other sections.
