Abstract The so-called 20-20-20 targets for the European Union include a reduction in
greenhouse gas emissions by 20% compared to 1990, 20% of primary energy from …

It is projected that, in the following years, the wind-energy industry will maintain its rapid
growth over the last few decades. Such growth in the industry has been accompanied by the …

In this study, the effect of deploying microtabs on performance improvement of a horizontal
axis wind turbine blade is numerically investigated in three-dimensions. The NREL Phase …

Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge
and perpendicular to the surface. A study to find the optimal position to improve airfoil …

The single-channel jet control strategy, with a suction slot on the upper surface and an
injection slot near the trailing edge on the lower surface, has the dual benefit of both …

Based on the single-channel jet control strategy with a suction slot on the upper surface and
injection slots near the trailing edge on the lower surface, proposed in this work is a novel …

Multiobjective optimisation and integrated aerodynamic-structural design of wind turbine
blades are emerging approaches, both requiring significant number of high fidelity analyses …

Increased aerodynamic loads during gusts, turbulence, and maneuvers define the outer
envelope of aircraft structural design. Minitabs, which are small spanwise strips that protrude …

In the last decades, wind turbine innovation has led to significant growth in capacity and size
per turbine. Consequently, the blade experiences additional local fluctuations due to local …

The effectiveness of trailing-edge flaps and microtabs in damping 1P-3P loads has been
proven through a series of research work during the past decade. This paper presents the …
