抄録

Flow around a rotating Darrieus turbine was simulated by solving 2-d Navier-Stokes equations. The equations were discretized by the Finite volume method for space and the Fractional step method for time. The convection terms were specially discretized by an upwinding scheme for an unstructured grid. In this report, single-blade and two-blade turbine without the duct were simulated. Values of the parameters were as follows : blade section, NACA 0018 ; and Reynolds number, 3×10⁵. The results showed good agreement with experimental data in the following point : optimum tip speed ratio decreases inversely with solidity. Simulated flows were visualized by stream lines, vorticity, pressure distribution, and streak lines. The visualized flow fields can explain the torque-generating mechanism.
