Abstract

This paper deals with an experimental study of the vortex structure of interacting coaxial swirling flows in an isothermal model of adaptive burner used for combustion of low-grade fuel. The working section consists of two consecutively connected tangential swirlers. Depending on the method of liquid flow supply to the second stage, both co-swirl and counter-swirl of two flows occur in the working section. In experiments, the effect of the flow swirl method on the resulting flow structure was studied with varying flow rates. Time-averaged distributions of axial and tangential velocity components along the entire region of the resulting flow were obtained using laser-Doppler anemometry. Experimental results have shown that counter-swirl is more preferable for the use in a two-stage burner because it promotes faster mixing of the burner jets of the first and second stages and more uniform filling of the internal volume of device.
