An apparatus for flow visualization around oscillating wing was designed and assembled. To validate the modern CFD. the experimental data not only about the pressure distributions on the wing surfaces but also the flow patterns around the wing are needed. The present system aims to offer the experimental information on the flow patterns around oscillating 2-D wings. In this report, the outlines of the driving mechanism for the 2-D wing and the smoke generator are presented together with the related other devices. It is shown that the system works well in the low-turbulence wind tunnel at NAL and expected that it can be used for the research of low speed unsteady aerodynamics and aeroelasticity.
