Abstract
The aerodynamics of a laboratory model of an improved furnace with a four-vortex coal combustion scheme 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. Comparison of the experimental results with previous PIV measurements shows that they are in good agreement.
