- Quasiperiodicity, a partially synchronous state that precedes the onset of forced synchronization in hydrodynamic systems, exhibits distinct geometrical patterns based on the specific route to lock-in. In this study, we explore these dynamic behaviors using recurrence quantification analysis. Focusing on a self-excited hydrodynamic system-a low-density jet subjected to external acoustic forcing at varying frequencies and amplitudes. We generate recurrence plots from unsteady velocity time traces. These recurrence plots provide insight into the synchronization dynamics and pathways of the jet under forced conditions. Further, we show that recurrence quantities are helpful to detect and distinguish between different routes to lock-in.
