The deflection and unsteadiness of the supersonic streamwise vortex interacting with the compression waves
The deflection and unsteadiness of the supersonic streamwise vortex interacting with the compression waves are experimentally investigated using a nanoparticle-based planar laser scattering technique. Under the influence of the compression waves, the spatial evolution of the vortex is significantly different from that of the undisturbed vortex. The diameter of the vortex core decreases continuously due to adverse pressure gradient, with a statistical reduction of approximately 19.1% at the most downstream position of the compression waves. Analyses of gray fluctuations reveal that the compression waves significantly increase the unsteadiness of the vortex.
