SINOPSIS

An experimental study has been conducted in a water channel to examine the structure of laminar jets issuing orthogonally into a cross-flow from a pipe extending far away from the channel's free surface and wall boundary layers; interest has been focused on the range of jet momentum fluxes that are significantly lower than the cross-flow momentum flux. Three familiar types of coherent structures have been identified: von Kármán vortices, a pipe-end vortex, and shear-layer vortices; an additional pattern, previously observed in a cursory manner only and presently termed "tendrils," has been found to appear under certain conditions. All types of structures have been documented qualitatively and quantitatively. The various physical mechanisms for the generation and evolution of vorticity throughout the flow have also been discussed.
