AB  - The controlled modulation of the nozzle exit velocity acts as a disturbance source, superimposing the natural disturbances in axisymmetric turbulent air jets. The modulation controls the vortex roll-up, and thus the overall vortex structure in the jet. The vortex structures have a significant influence on the heat transfer properties of the jet configurations. The jet can be modulated by an external source of low amplitude oscillations or by self-sustaining oscillations generated by the operation of the specially designed whistler nozzles. The aim of the experimental investigations, mathematical modelling and numerical simulations was to investigate the properties and vortex structures of acoustically modified and non-modified jets and to find an efficient way to control them.
This study can serve as a basis for further development and optimisation of technological processes related to air nozzles. The paper presents the results of experimental research and mathematical modelling and numerical simulation of free and impinging turbulent axisymmetric modified and not modified air jets.
