Description
Summary:This study presents three-dimensional numerical simulations of the flow around a straight-bladed Darrieus turbine using an active synthetic jet flow control method. Turbine performance is analyzed quantitatively by studying hydrodynamic coefficients (torque coefficient, tangential force coefficient and normal force coefficient) and qualitatively by flow behavior (vorticity fields, pressure fields and velocity fields). The simulations were carried out by solving the Reynolds-averaged Navier-Stokes equations (RANS) in Star CCM + with the SST k-w turbulence model. The numerical results show that the use of synthetic jets on the aerodynamic profiles increases the net torque and the power output of the turbine. Furthermore, the power consumption of the synthetic jets is less than the increase in power generated in the turbine. Therefore, it is shown that the efficiency of the turbine increases through the use of synthetic jets.
