On the topology patterns and symmetry breaking in two planar synthetic jets

This article studies the flow structures and main patterns driving dynamics in one two planar synthetic jets. We perform numerical simulations at different Reynolds numbers (Re), for a similar forcing frequency, to model jet jets, which present movement in-phase (synchronous jets) out-of-phase (asynchronous jets). identify types of regimes as function number: (i) is symmetric (ii) symmetry broken Re ≈110 ≈140 single synchronous respectively. On contrary, always asymmetric asynchronous calculate thrust produced by several configurations, finding that half jets; however, this quantity much smaller Finally, we use higher order dynamic mode decomposition dynamics. The solution periodic with frequency (St*) dominant mode. emerging rise amplitude low-frequency (St0 = St*/6) sub-harmonic number increases suggests connection between breaking. A new identified breaking periodicity.
