dc.description.abstractSmall-scale horizontal axis wind-turbines (SHAWTs) are acquiring relevance withinthe regulatory policies of the wind sector aiming at net-zero emissions, while reduc-ing visual and environmental impact by means of distributed grids. SHAWTs operatetransitionally, at Reynolds numbers that fall between 1 105<Re<5 105. Further-more, environmental turbulence and roughness affect the energetic outcome of theturbines. In this study, the combined effect of turbulence and roughness is analysedvia wind tunnel experiments upon a transitionally operating NACA0021 airfoil. Thecombined effects cause a negative synergy, inducing higher drops in lift and effi-ciency values than when considering the perturbing agents individually. Besides, suchlosses are Reynolds-dependent, with higher numbers increasing the differencebetween clean and real configurations, reaching efficiency decrements above 60% inthe worst-case scenario.Thus, these experimental measurements are employed for obtaining the power cur-ves and estimating the annual energy production (AEP) of a 7.8-kW-rated SHAWTdesign by means of a BEM code. The simulations show a worst-case scenario inwhich the AEP reduces above 70% when compared to the baseline configuration,with such a loss getting attenuated when a pitch-regulated control is assumed. Theseresults highlight the relevance of performing tests that consider the joint effect ofturbulence and roughness.en
