![]() ![]() This particularly suggests that the developed model could be used as a new trend to modify the designs of wind turbine blades. Therefore, it was deduced that the benefits of TEF with Micro-Tab were apparent, especially at the lower surface of the airfoil. The results showed that an increase in the maximum lift coefficient by 25% and a delay in the air-flow stall were accomplished due to opposite sign vortices, which was better than the standard airfoil and S-809 with TEF. As a tablature editor, it produces and prints tabs and musical notation staves. Finally, the effects of TEF with Micro-Tab on the aerodynamic characteristics of the S-809 with TEF were compared. TablEdit is a program for creating, editing, printing and listening to tablature and sheet music for mandolin, guitar, bass and other stringed, fretted instruments. Different Micro-Tab positions and constant TEF were examined. Thirdly, the influence of TEF with Micro-Tab on the flow behaviors of the airfoil NREL’s S-809 was studied and discussed. As a result, the effect of TEF on air-flow behavior was demonstrated by augmenting the pressure coefficient at the lower surface of the airfoil at flap position 80% chord length (C) and α F = 7.5°. Secondly, the effects of the flap position (H) and deflection angle (α F) on the flow behaviors were investigated. Firstly, a computational fluid dynamics (CFD) model for the airfoil NREL’s S-809 was established, and validated by comparison with previous studies and wind tunnel experimental data. In this paper, an attempt was made to evaluate the influence of TEF with Micro-Tab on the performance of NREL’s S-809 airfoils. In particular, the benefits generated by TEF with Micro-Tab may be of great interest in the design of wind turbine blades. This study focused mostly on the use of TEF with Micro-Tab in wind turbine blades using NREL’s S-809 as a model airfoil. ![]() Moreover, it can also be used to generate more lift and delay the onset of stall. Recently, the Trailing-Edge Flap with Micro-Tab (TEF with Micro-Tab) has been exploited to enhance the performance of wind turbine blades. ![]()
