Abstract:

This paper deals with the time dependent establishment of the flow field on an airfoil in unsteady flow. The impulsive start of the flow is achieved in a Water-Ludwieg-Tunnel. By using a coded particle tracing method for flow visualization, the detailed flow establishment on a NACA 0012 airfoil at 30 deg angle of attack is shown from the beginning where potential flow exists with zero circulation to a quasi-steady formation of the vortex street.
