Novel Operating Mode of a Fluidic Oscillator

Journal of Fluids Engineering, 2022
Abstract Fluidic oscillators show promise for use in aerodynamic flow control applications, with many studies reporting oscillation frequencies in the 1–10 kHz range. Spyropoulos, “A Sonic Oscillator,” introduced a “sonic” oscillator whose oscillation frequency depends on the inlet flow rate.
