چکیده
|
In this study,energy performance and aerodynamic forces acted on a vertical-axis darrieus wind turbine (vawt) have been examined by using computational fluid dynamics (cfd) program. numerical investigation is conducted on a blade fixed pitch vawt using naca0021,naca0015,naca5520 and clark-y airfoils as a blade profile to assess its performance,and these four airfoils were compared with each other’s. numerical simulation is done for two-dimensional unsteady flow around the vawt model by using ansys-fluent program which solves reynolds averaged navier-stokes equations. considered numerical results,naca5520 can be employed to generate first movement; in addition,the maximum average power coefficient has been obtained for naca0021. © 2017 tibtd printed in turkey.
