Experiments were performed to quantify the interaction of a streamwise vortex with a series of oblique shock waves using stereoscopic particle image velocimetry. For these experiments, the streamwise vortex was created using a diamond-shaped, finite-span wing, pitched to one of two angles of attack $(\alpha =5^{\circ },{10}^{\circ })$. Downstream of the wing, the streamwise vortex encountered a two-dimensional oblique shock, generated by a wedge $(\theta ={15}^{\circ },{20}^{\circ },{25}^{\circ })$, resulting in a series of weak and moderate oblique shock-vortex interactions. While only moderate interactions produced a conical shock distortion, all interactions resulted in appreciable changes to the flow field downstream of the shock. These changes were reflected in increased velocity deficits and induced rotational motion; in the case of moderate interactions, increased turbulence kinetic energy was also apparent.
