The three-dimensional, quasi time-resolved flow fields of spatially oscillating jets at various skew angles, velocity ratios and oscillation frequencies are examined experimentally to extend the scope of earlier studies that are limited to one skew angle only. The spatially oscillating jet is emitted by a fluidic oscillator. The velocity fields are acquired plane-by-plane using a stereoscopic particle image velocimetry system. The results are phase-averaged based on pressure signals from inside the oscillator. The study describes the underlying mechanisms of the dominant streamwise vortices created by the interaction between the oscillating jet and the crossflow using analogies to steady jets. For small Strouhal numbers, the flow field behaves similar to that of a vortex generating jet with changing deflection angle. For higher Strouhal numbers, the crossflow experiences a steady, wide-spread jet. When a skew angle is introduced, the flow field becomes asymmetric and the vortex dynamics change. With decreasing skew angle, one of the alternating vortices diminishes until at a skew angle of 45◦ only one vortex dominates the time-averaged flow field at small velocity ratios. At a skew angle of 0◦(ie, the plane spanned by the oscillating jet is parallel to the direction of the crossflow), the penetration into the crossflow is comparable to that of a steady jet. Moreover, a pair of counter-rotating, simultaneously existing vortices similar to that know from steady jets is identified. Similar to earlier studies, the flow field at a given velocity ratio is independent of the oscillation frequency because velocity ratio and Strouhal number are linearly proportional.
