Abstract The aerodynamics of a laboratory model of an improved four-vortex coal combustion furnace is studied using laser Doppler anemometry. For the isothermal case, the distributions of the averaged velocity and velocity pulsations are obtained for various flow regimes. The main features of the flow are established. The experimental results are compared with previous particle image velocimetry measurements, showing good agreement.
