In this study, a novel fluidic oscillator suitable for use as key component of flow control device is proposed and investigated through numerical simulations. The new layout adds resonators to typical with dual feedback channels, the length loop designed be adjustable. This movable channels can generate jet an adjustable frequency, it has smaller total pressure loss than baseline model. Numeric...

Abstract In recent years, fluidic oscillators have been actively applied as devices for flow control in the field of aero and hydrodynamics. This study aims to investigate structure a sweeping jet ejected from oscillator into confined area – slot channel. Dynamics are investigated using PIV method with high temporal resolution. The effect Re number on oscillation frequency was studied range 1 5...

Abstract This experimental study investigates the effects of internal geometry modifications on performance a curved Sweeping Jet actuator. The are applied to feedback channel and mixing chamber Coanda surface, resulting actuator properties evaluated using time-resolved static pressure measurements inside hot-wire external flow. major result is that small, localized sweeping jet can lead comple...

A fluidic oscillator with a bent outlet nozzle was investigated to find the effects of bending angle on characteristics and without external flow. Unsteady aerodynamic analyses were performed internal flow two feedback channels interaction between jets NACA0015 airfoil. The using three-dimensional unsteady Reynolds-averaged Navier-Stokes equations shear stress transport turbulence model. tested...
