The behavior of the vortical structure in a two-dimensional jet was investigated by the feedback excitation method use the fluctuating velocity with the phase-shift. The experiments were carried out at exit velocity of 10m/sec and two-dimensional nozzle of aspect ratio 14 and Reynolds number is 1.42×10^4 based on the nozzle height. The jet is excited by the disturbance fed into the jet at the nozzle lips, the excitation intensity u'/U_<eo> was fixed on 0.04. The effect of excitation was investigated by measuring mean velocities, the fluctuating velocities, and the power spectrum densities. The result suggests that the behavior of the vortical structure is manipulated by use the signal with the phase-shift.
