Abstract
Fluidic oscillators are non-moving part fluid valves that generate a self-sustained, stable oscillating flow and pressure. This research involves an experimental investigation of one geometrical configuration of bi-stable Supersonic Fluidic Oscillator (SFO). The experiments are conducted over a range of supply pressure, control channel flow resistance and exhaust chamber pressure values for the purpose of determining their effect on the device oscillation frequency and amplitude. High-speed Schlieren videos of the internal flow field were made and synchronized with experimental pressure values taken at strategic locations, to provide insight into the device switching process. The experimental results were also used to validate a computational fluid dynamics model and conversely, the model was used to better understand the mechanisms responsible for the oscillation.
