Аннотация
The results of numerical simulations of a jet discharging from a narrow slit at low Reynolds numbers Re are presented. A comparison with the data of laboratory experiments is performed, and it is shown that steady numerical solutions with increasing Re transform into unsteady solutions with self-excitation of sinusoidal instability. Lateral oscillations are superimposed at the inlet section, and their influence on the jet behavior is studied.
