Axisymmetric Synthetic Jet Actuators with Large Streamwise Dimensions

Popis výsledku v původním jazyce

This study analyzes the resonant behavior of synthetic jet actuators with large streamwise dimensions, that is, synthetic jet actuators with nozzle and/or chamber lengths comparable with the sound wavelength. Analytical models that capture the effects ofthe large streamwise dimensions of the actuators are introduced for natural frequencies, velocity resonance curves, and phase shifts. Velocity measurements were obtained using a hot-wire anemometer at the nozzle outlets of four synthetic jet actuator configurations. The velocity amplitudes and phase characteristics were evaluated from experimental data, and higher-order resonances (up to the fifth order) were revealed. The theoretical natural frequencies, velocity resonance curves, and phase shifts were compared with the experimental results and found to be in qualitative agreement.
