Abstract
- Structural characteristics of the strong interaction between an oblique shock wave and streamwise vortex are experimentally investigated based on the nanoparticle-based planar laser scattering technology. Fine structures of reorganized vortices and helical structures are first recorded in experimental visualization. For the case with the strongest shock wave, a catastrophe process occurs due to the change of breakdown type, which gives birth to abundant small-scale vortical structures. Fractal and feature analyses indicate that the turbulent mixing dramatically increases after the interaction, especially for the case with spiral breakdown. [ABSTRACT FROM AUTHOR]
