LDA diagnostics of the flow structure in the model of an advanced four-vortex furnace

Abstract

In this work, the internal aerodynamics of a laboratory model of a promising furnace with a four-vortex scheme for burning coal fuel is studied using the method of laser Doppler anemometry (LDA). Distributions of the averaged velocity and velocity pulsations are obtained in various areas of the furnace model in a wide range of regimes. The main features of the flow are identified. The experimental results are compared with the previous measurements by the PIV method; their good agreement is achieved. The data obtained are used to verify the mathematical model in numerical studies of a full-scale furnace.
