Abstract
Flow around rotating Darrieus turbines were simulated by solving 2-d Navier-Stokes equations. The equations were discretized by the Finite Volume Method for the space and Fractional Step Method for the time. In this report, 2-type turbines were simulated, that is, ducted turbine and non-ducted turbine. In the case of ducted turbine, Composite Grid scheme was introduced. The results showed good agreement with experimental data in torque coefficient, blade efficiency, etc. Simulated flows were visualized by stream lines, vorticity, pressure distribution, streak lines, etc. The visualized flow fields can explain the torque-generating mechanism.
