Abstract: The Potential of wind energy globally is very bright. This research aims to improve aerodynamics, aeroacoustics and controllability of a 3-D horizontal axis wind turbine. Advanced flow control techniques are required to improve rotor blade performances. Trapped vortex cell (TVC) was chosen in this research work, as a promising flow control tool. Effectiveness of the TVC, requires a well-designed cavity shape located in chordwise direction on the upper surface of the airfoil. Under certain flow conditions, a steady vortical structure forms inside the cavity creating a circulatory flow motion closed by the dividing streamline. TVC will be coupled with a suitable active flow control technique in order to reduce the flow separation and consequently the blade pressure drag level. Intelligent rotor blade equipped with sensors and various regulation will be designed. The objectives of this project are:
  • Design and optimization of a trapped vortex cell (TVC) coupled with an active flow control using ANSYS fluent as a design tool.
  • Assessment of the TVC/active flow control technique effect on the aerodynamic performance of the rotor blade using Ansys-Fluent.
  • Investigating the complex unsteady phenomena taking place in the cavity trapping using particle image velocimetry (PIV).
  • Verify CFD simulation by wind tunnel experiments using particle image velocimetry as flow field measurement technique
