Abstract
We consider a steady submerged swirling laminar jet of viscous incompressible fluid flowing out of a tube and spreading along a solid plane. Numerical solution of the Navier–Stokes equations indicates that the jet is self-similar at large distances from the outlet of the tube and the self-similarity exponent is approximately the same to the one of the non-swirling jet. The symmetry of self-similar dimensionless velocity profiles at low values of self-similar variable is discorvered. The presence of the zero radial velocity locus, shape of which is dependent on the swirl, is established.
