Web15 de ago. de 2024 · The vortex T-mixer flow is characterized by a single dominant vortex, the stability of which is closely coupled to the appearance of vortex breakdown. Specifically, at a Reynolds number of Re≈ 90, a first vortex breakdown region appears in the steady-state solution, rendering the vortex pulsatively unstable.
