The method of laser Doppler anemometry was applied for study of the spatial structure of a swirl turbulent flow occurred in isothermal lab-scale model of a vortex furnace (“CBTI design”). The criterion of “minimum of total pressure” was applied for visualization of a vortex core; the latter possesses a W-shaped geometry. Velocity and pressure pulsation spectra were measured for a wide range of operational parameters; these spectra testify about zero precession of a vortex core.
