Abstract
The article presents the results of a numerical study of flow control in a submerged round jet using harmonic perturbations at the lateral boundaries simulating sound sources. The analysis of distributions of instantaneous and time-averaged components of the velocity vector is performed, and physical effects occurring in the excited jet are revealed. At certain values of the Strouhal and Reynolds numbers, a bifurcation occurs in the jet caused by acoustic excitation, as in other studies with mechanical forcing or disturbances of the inlet velocity profile. The effect of the transition from one to two loudspeakers located on opposite boundaries on the mean velocity field and the jet flow structure is studied.
