Abstract |
The global objective of WOAC project is to develop novel techniques to improve the performance and operating range of wind energy
devices consisting of large Horizontal Axis Wind Turbines (HAWTs), affecting the intermittency of these systems and the cost of the energy
generated. The improvement of performance will be based on the use of Active Flow Control devices that will control flow separation,
allowing for an improvement of performance in different operating conditions, a reduction of the cut-in wind speed, and an increase of the
cut-out wind speed.To achieve the objectives of the project, two main subprojects are considered:
The first subproject will evaluate the performance of airfoils of the turbine blades by means of 2D and 3D computational fluid dynamics
(CFD) simulations, with and without AFC actuation, to obtain the airfoil polar curves in both situations.
The second subproject will use the information obtained from the first subproject to optimize the performance of the entire blade under
different operating conditions, and when considering AFC actuation in several or all the airfoils. The selective optimization of the AFC
actuation in each airfoil shall enhance the overall blade performance under any of the operating conditions considered.
The main activities of the second subproject will be concentrated in WPs 3, 4, 5, and 7 of the globalproposal.
WP3 will be dedicated to the obtainment of a surrogate model based on the simulations performed in WP1 and WP2. This surrogate model
shall be used as a tool to compute the polar curves for the considered working conditions and for any combination of AFC parameters. The
objective of the surrogate model is to reproduce with satisfactory accuracy the effects of the angle of attack (AoA) and the AFC parameters
(and their cross-correlation) on the aerodynamic force coefficients.
WP4 will use the surrogate model developed in WP3 to determine proper AFC and AoA combinations allowing to optimize the
performance of each airfoil in an independent manner. This implies that 1) for each wind speed, the optimization will have a common
objective (either to re-attach the flow in all the baseline sections showing separation or the opposite) and 2) the load constraints of the
HAWT will not be considered. The results of this WP will be a set of polar curves highlighting the upper limit of the AFC actuation with
regard to its ability to modify the flow.
WP5 will be dedicated to the study of advanced aerodynamic configurations through a further study and characterization of the problem
from a fluid dynamics standpoint. This will be done by revisiting some of the assumptions and limitations of the 2D numerical models
developed for the baseline simulations and AFC model. In WP5 the main contribution from CIMNE will be a 3D flow study using mid fidelity
simulations.
WP7 will be dedicated to the study of 3D effects of AFC actuation near cut-out speed. The main contributions of subproject 2 to WP7 will
be the study of the performance of AFC near cut-out speed and the increase of cut-out wind speed |
