Determination of hydrodynamic forces acting on the blades of Darrieus turbine used to harness water energy from dams, rivers and ocean is very important to evaluate this turbine performance. Therefore, this paper presents the numerical results of CFD investigation using K-ε closure turbulence model. This simulation has been performed for a hydro Darrieus turbine that we have previously tested experimentally; this turbine has a diameter of 21.5 cm and it is composed of three NACA0020 blades, with a height of 23 cm and a cord of 7 cm, that are fixed with a separation angle of 120 °. The present simulation has been carried out for a water flow velocity of 0.67 m/s and the Darrieus turbine rotating velocity of 125 rpm. These values correspond to a specific velocity λ equal to 2, a flow Reynolds number Rev equal to 4.57 104, a rotational Reynolds number Reu equal to 1.97 105 and a relative Reynolds number Rew varying between 4.72 104 and 1.39 105. The graphical presentations of the simulation numerical results have shown practically identical curves, respectively for the hydrodynamic lift and drag forces variations versus the rotational angle (position angle of each blade) with a phase angle of 120° between the first blade and the second one and of 240° between the first blade and the third one. The hydrodynamic blade element lift force varies between 0.0454 and 0.641 N while the drag force varies between - 0.0968 and 0.342 N. The global turbine hydrodynamic lift and drag forces (for the three blades elements together) varies respectively between 0.5928 and 0.9251 N and between 0.0335 and 0.2497 N. The maximal values show that the lift is about twice the drag for each blade and about four times for this turbine. The turbine average lift and drag forces over three rotations are respectively 32.38 N and 6.61 N.
