The subject of this paper is the submerged, round, unconfined turbulent axisymmetric jet, which issues from nozzles with different geometries and impinges to the flat heated plate positioned normally to the jet axis. The aim of experimental investigations, mathematical modeling and numerical simulations is to widely investigate properties and the vortex structures of modified and unmodified jet,that are assumed to have great importance in the heat transfer process. It is found that the vortex roll-up can be controlled by adding small amplitude modulation of the nozzle exit velocity using external source of low-amplitude oscillations or self-sustained oscillations generated in the operation of the specially designed whistler nozzles.
