AbstractIn this paper, a numerical study of self-induced flow motions of non-circular jets is described to investigate the underlying mechanism of shock/vortex interaction, and axis-switching of the primary vortex loop in its initial stage. Numerical results were obtained by solving three-dimensional Euler equations with a dispersion-controlled scheme and displayed in the form of iso-vorticity surfaces. From the results, it was concluded that secondary flows, secondary shock waves and axis-switching play an important role in the jet instability development, and these are also the primary driving forces leading to the generation of hairpin vortices and complex coherence structures.
