Abstract: The control of a turbulent round jet is experimentally investigated based on the injection of two radial minijets, separated azimuthally by an angle theta = 60 degrees, prior to the issue of the main jet. It has been found that the asymmetric excitation increases the decay rate of the jet centerline mean velocity by 30 % or more than the symmetric (theta = 180 degrees). A flapping motion of the jet column is found to be responsible for the substantially increased jet mixing.
