Supercritical Regimes in Axisymmetric Submerged Jets
The bifurcation of secondary regimes in jet flows of a viscous incompressible fluid is studied. Initial axisymmetric submerged jets having velocity distributions from Schlichting’s self-similar profile to the “top hat” form are considered as parallel. In the latter case the secondary regime was found to include stationary rotation around the jet axis. The rotation is generated in jets with high-gradient profiles and is absent in the case of the self-similar distribution.
