Progress in wind tunnel experimental techniques for wind turbine

Based on the unsteady aerodynamics experiment (UAE) phase VI and the model experiment in controlled conditions (MEXICO) projects and the related research carried out in China Aerodynamic Research and Development Center (CARDC), the recent progress in the wind tunnel experimental techniques for the wind turbine is summarized. Measurement techniques commonly used for different types of wind tunnel experiments for wind turbine are reviewed. Important research achievements are discussed, such as the wind tunnel disturbance, the equivalence of the airfoil inflow condition, the three-dimensional (3D) effect, the dynamic inflow influence, the flow field structure, and the vortex induction. The corresponding research at CARDC and some ideas on the large wind turbine are also introduced.
