N2 - Large-eddy simulations are performed to investigate the internal dynamics of a fluidic oscillator over a range of Reynolds numbers Red = 3000 - 30000. The device represents Φ-shaped configuration providing a strongly unsteady flow due to periodic oscillations based on the Coanda effect. Computational results for a mesh convergence study are presented. The conducted analysis of statistical characteristics of the flow has shown that the flow velocity in the feedback channels increases with an increase in the Reynolds number. The obtained results, such as the frequency of vibrations and the depth of the jet, perfectly match the experimental data.
