abstract

  • The interactions of the slow flow induced by the entrainment of axisymmetric jets and plumes with the surrounding geometry may result in the appearance of azimuthal swirling motion. This swirling flow evolves as it approaches the jet (or plume) as a result of the action of viscous forces on the solid surfaces bounding the fluid domain. When the initial size of the jet or plume a is much smaller than the characteristic radial distance R at which the swirl is generated, the evolution of the flow leads to a self-similar description with weak swirling motion, valid at intermediate radial distances R such that a<
