Numerical Study For Slotted And Vibrated Asymmetric Aerofoils
The aerodynamics of slotted aerofoils under various Reynolds numbers were numerically studied. Moreover, vibration of aerofoils due to the wind flow was also investigated. Different Reynolds numbers (0.25, 0.4, 0.7 and 1) ×106 were utilized using an Ansys noncommercial version. A slotted asymmetric aerofoil, which was NACA4412, was chosen to implement the concept of the current investigation. The base aerofoil was compared to an experimental study to check the number of cells above and around the aerofoil. The slotted aerofoil appeared to have more momentum on the suction side. Moreover, the slotted aerofoils then subjected to an oscillatory motion due to the wind flow with 15Hz frequency.
