Three-component diagnostics of swirling flow in the model of an improved four-vortex furnace

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 four-vortex furnace. vortex cores with shape deformed vertical elliptical cylinder is visualized using ?minimum total pressure? criterion. spectrum velocity pulsations indicates absence unsteady periodic structures, which means occurrence stable volume combustion chamber.
