Oliver Paschereit, Hermann-Föttinger-Institut, Technische Universität Berlin, Berlin, Germany DOI: The presented video illustrates the experimentally acquired time-resolved flow field of a spatially oscillating jet in crossflow. The jet’s oscillation plane is perpendicular to the cross flow over a flat plate. The ratio between jet velocity and freestream is three and the oscillation frequency is 67 Hz. A traversable stereoscopic Particle Image Velocimetry system is employed to acquire velocity information. The time-resolved, three-dimensional
