Abstract
We investigate the oscillation phenomena occurring when a two-dimensional p lane jet emerges from a rectangular nozzle into a cavity with a body inside . It is shown that far from the lower oscillation limit, the frequencies of self-sustained oscillations are only governed by geometrical parameters. T he evolutions of the Strouhal versus Reynolds number show that the effect o f the geometry downstream the bluff-body is important for the control of th e oscillation mechanism.
