内容記述 | One of the vertical axis wind turbines that utilize drag force is the Savonius turbine. Savonius turbines are characterized by low speed rotation and high torque, so they are rarely used for wind power generation but have possibility to apply to ocean current power generation, which has been attracting attention recently. In this report, we actually performed a numerical simulation of the flow using suitable grid, focusing mainly on the case where four wind turbines are rotating in reverse at a constant speed, and investigated the state of the flow field. Two-dimensional incompressible Navier-Stokes equations are adopted as the basic equation and solved numerically using the finite difference method. In addition, in order to enable calculation even in a high Reynolds number flow, the nonlinear term of the equations are approximated by using the third-order accuracy upstream difference method. The simulations are performed with 0 degrees flow and 45 degrees flow for four turbines position. The flow field differs greatly depending on each angle, and the interaction between the wind turbines has been clarified. | |||||||||
