New Fluidic-Oscillator Concept for Flow-Separation Control
Original language description
Anovel fluidic oscillator, particularly suitable to serve as the key element in actuators for control of fluid flows, was proposed and experimentally investigated. Its core part, as in known oscillators, is a fluidic bistable jet-deflection diverter amplifier. The unique feature of the new layout is the absence of the closed feedback loop channels. Instead, there is a quarter-wave Helmholtz resonator tube connected to one of the amplifier control terminals. The acoustic waves traveling in it and reflected from its open end cause the phase-delayed switching of the amplifier. The main advantage is high achievable oscillation frequency and no dependence on the flow rate.
