Abstract
The problem of the interaction between two oppositely swirled jets of viscous incompressible fluid issuing from parallel tubes into the submerged space is considered. The scenario of the confluence of the two jets into a single jet is determined on the basis of a numerical solution. It is shown that far from the sources the flow is described by the self-similar axisymmetric Landau solution for a single swirled jet. The longitudinal vorticity field far from the source is also self-similar, with a complex decay rate. The asymptotic structure of the far field of the jet is discussed.
