The effects of pure tone acoustic fields upon the mean flow in a low Reynolds number turbulent plane jet were investigated experimentally. It was found that the main region flow can be altered by moderate level disturbances over a range of disturbance frequencies. The effects were observed to extend to distances of 80 nozzle widths downstream of the nozzle, while decaying with downstream distance, and to be linked to the turbulence behavior of the initial region shear layers.
