| Popis: | since early times has recorded history, the people have been utilized wind energy. Wind energy is one of the renewable energy sources and the wind turbine is used to generate electrical energy by the rotational rotor (mechanical energy). The favored form of turbine used for research is the horizontal axis wind turbine (HAWT) with winglets and optimization blade. Blade element momentum (BEM) was used for the design of the blades with 15 segments and the computational fluid dynamics was carried out using fluent for fluid flow through a process using a transient mode and RANS method to solve the problem during an experimental data at the wind tunnel. For the experimental process, the wind tunnel is used for test section on HAWT with velocity variations. The result show, that adding a winglet to existing a blade can change the downwash distribution leading to increased produced power and decrease an induced drag on a long blade, with lower tip speed ratio (TSR), winglet currently give a good starting torque for increase the power of wind turbine. |
