abstract

The frequency response of a trailing vortex downstream the free end of a NACA0015 wing section has been studied in a closed loop wind tunnel. The wing spanning approximately half height of the wind tunnel section was fixed to a dynamic load cell at the base. The flow cases studied have constant angle of attack of 10 degrees and constant Reynolds number of 160,000 based on the wing chord length while two levels of 0.5 and 4.6% free-stream turbulence were introduced to the flow. Lift and drag forces acting on the wing section were quantified using a load cell while an X-probe hot-wire was used to measure the turbulence parameters in the near-field wake region. The tip vortex was captured with sufficient accuracy. The effect of free-stream turbulence on the vortex structure has been discussed in detail by characterizing several turbulence parameters via time-averaging and frequency analysis of the turbulence signal.
