Abstract

The effect of solid particles on the flow structure of a round air jet in a stagnant surrounding was investigated experimentally. Information on the averaged two component velocities the kinetic energies, and the shear stress properties were obtained for both phases by means of a monochromatic three beam laser Doppler anemometer. The particle number density was also measured by this system. Glass beads of 64MUm and 132MUm diameter were used for a constant mass loading ratio of 0.3 in a jet with a Reynolds number of 20,000. The lateral mean velocity and number density profiles were expressed by best fitting functions and several invariable coefficients were found. The standard drag force coefficient CD for a single particle was applicable for a dilute particle cloud even in a non uniform air velocity field.
