title = "Effects of a contraction on a uniformly rotating flow",
abstract = "This article addresses the problem of the generation conditions of a high-Reynolds swirling jet, which to our knowledge has never been dealt with precisely in past experimental studies. We observe that the exit plane of a jet generated with a converging nozzle is progressively invaded by turbulence that is not related to the dynamics of the developing jet, but to the upstream contracted duct flow. Using an inviscid axisymmetric steady model for this flow and a stability analysis derived from rapid distortion theory, we find that part of this turbulence can be explained by an accumulation of small-scale centrifugal instabilities on the flow trajectories. Detailed analysis of the steady solution also suggests the possibility of a wall separation inside the converging nozzle at sufficiently high rotation rates.",
