AbstractThe induced deformation, due to the presence of elastic coupling in the structure of passive smart blades, is the key parameter that affects the wind turbine performance. Therefore, when predicting the aerodynamic performance of these turbines, a structural analyser is also required to bring the effect of the induced deformation into account. This diverts the numerical simulation of wind turbines utilising passive smart blades from the simulation of wind turbines with traditional blades. In performance prediction, additional complexity arises when the blades are bend-twist-coupled. In this case an iterative coupled-aero-structure analysis must be carried out. Further difficulties in simulation of these turbines are posed by the fact that the current analytical models for analysis of structures made of anisotropic composite materials are not accurate enough. Different strategies have been proposed and followed by investigators to embark upon the above highlighted problems. The present paper describes, evaluates and compares these approaches.

A stall-regulated wind turbine design to reduce fatigue

“…trailing edge flaps and microtabs) to alleviate fatigue loads increases the complexity, mass and maintenance costs of wind turbines. While the trend in current research focuses on alleviating the loads of VS-PC wind turbines using active flow controllers [7][8][9][10], the present paper highlights the potential benefits of employing variable-speed stall-regulated (VS-SR) wind turbines. In particular, this paper seeks at raising interest in fatigue and transient power reduction by taking advantage of the low aerodynamic sensitivity of stalled blades.…”

A strongly-coupled model for flexible rotors

“…The most used models are the simple Euler-Bernouilli rod model [6] and the nonlinear ribbon model [7,8] with an intrinsic non-linear coupling between bending and twisting. Several authors have studied the effect of this coupling on the adaptability of the rotors to non-optimal operational conditions [9,10,11]. In the present work, we shall use the simple rod model.…”
