Abstract: In general, the behavior of science and engineering is predicted based on nonlinear math models. Imprecise knowledge of the model parameters alters the system response from the assumed nominal model data. One proposes an ...

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 ...

Abstract: Abstract. This paper describes the experimental characterization of a no-moving-parts, plasma-switched, two-stage, fluidic vortex valve capable of throttling Mach-0.85 air-flow at 5 bar. In the first stage, a sparkjet is ...
