Typical experiments were carried out in a small, low-speed wind tunnel to obtain the mean and fluctuating flow fields of an airfoil with a deflected spoiler using a two-component laser doppler velocimetry (LDV) system. The mean wake profiles and turbulent shear stresses were evaluated and compared with the available hot-wire and predicted results. Velocity and turbulent stress contour plots are also presented. Hot-wire results were not available close to the trailing edge because of the reverse flow. The predicted results were evaluated using a two dimensional vortex tracing method. The hot-wire anemometer gives reasonably accurate results where there is no reverse flow and the flow is not highly turbulent. The LDV gives accurate results close to the trailing edge where other methods fail. In general the LDV results are in better agreement with the calculated results.
