N2 - The paper presents the results of experimental investigation of circular jets forming as the Dean vortices modulate them at the curved channel exit. Some features of the jet flow are analyzed under the conditions of interaction between the Dean vortices and the Kelvin-Helmholtz ring vortices which results in the jet evolution different from that observed as the jet is generated behind circular and flat nozzles at the straight channel exit. In turn, the variations in the flow structure influence the regime of the diffusion jet combustion. The effect of Dean vortices on combustion of hydrogen and its mixture with oxygen and that of propane is analyzed in this paper. Flame transformation under forcing of external acoustic waves at a proper frequency stimulating flow instability is discussed.
