THREE-COMPONENT DIAGNOSTICS OF SWIRLING FLOW IN THE MODEL OF AN IMPROVED FOUR-VORTEX FURNACE

ABSTRACT
The spatial structure of a swirling turbulent flow has been investigated based on the three-component laser Doppler anemometry method in an isothermal laboratory model of a four-vortex furnace. The structure of the vortex cores of the flow with the shape of a deformed vertical elliptical cylinder is visualized using the “minimum total pressure” criterion. The spectrum of velocity pulsations indicates the absence of unsteady periodic vortex structures, which means the occurrence of a stable vortex flow in the volume of the combustion chamber.
