RÉSUMÉ

The paper reports on the results of experimental and numerical studies of the structure of coaxial jets with swirling and combustion under different buoyancy conditions. It is shown that the angle of the jet orientation relative to the vertical direction strongly affects the velocity components and change in swirling along the jet curvilinear axis. On the other hand, it is shown that the influence of the initial swirling of the jet significantly determines the flow dynamics as well. PIV and CFD studies carried out for the near field of the jet give good agreement in terms of the axial velocity component. These studies allow explaining the maximum value of the mass rate of the burnout U in the range of buoyancy orientation angle 30° < θ < 60°. This fact can be helpfully used for the creation of new different-purpose energy-efficient burners.
