A cubic open type chamber was designed and built in order to produce nearly Homogeneous and Isotropic Turbulence field (HIT) at the cube center, with low mean velocity. This was accomplished by mixing eight synthetic jets in ambient atmosphere all pointing towards the center. The power and frequency of excitation of the specially made jet actuators were varied and the flow characteristics of the resulting flow field were monitored. Flow visualization and image processing were employed in order to examine the interaction of a free jet and a smoke plume with the synthetic turbulent field.
