Global hydrodynamic stability of swirling jets

 

Swirling jets are canonically used in reacting flow systems with the well-known application of the swirl-stabilized flame. However, swirl induced flows often give rise to unsteady vortical, hydrodynamic structures. In combustion, these unsteady structures couple with combustor acoustics and heat release oscillations to cause the well-known thermoacoustic instability. Thus, accurate and efficient modeling of the unsteady hydrodynamic structures presents a serious challenge in current thermoacoustic systems literature.
