Abstract
The linear BiGlobal stability analysis is used to investigate the transition from a globally stable state to a globally unstable state (flapping oscillation) in planar fountains (negatively buoyant jets). The critical conditions for the onset of flapping oscillation and its corresponding frequency are predicted using global stability analysis for fountains with a jet-to-ambient density ratio of 0.95. The results from the global stability analysis are favorably compared with unsteady numerical simulations and the available experiments in the literature.
