We study a turbulent jet generated by a fluidic oscillator using Large-eddy simulations in a range of Reynolds numbers Re d = 3000−30000. The device represents Φ-shaped configuration providing a strongly unsteady flow due to periodic oscillations based on the Coanda effect. Several simulation results are presented for a mesh convergence study, the analysis of the time-averaged statistics as well as the oscillation frequency against Re d .
