SINOPSIS

The results of measurements of energy parameters of electrogasdynamic actuating elements, functioning based on near-surface dielectric barrier discharge (DBD) and intended for boundary layer flow control are presented. Five various models of DBD actuators were tested. These models differed in the number of external electrodes and their geometry. The discharge was excited by the generator, which formed electrical voltage pulses of alternating polarity with amplitudes of 1-5 kV, duration of 20 s, and frequencies of 5-8 kHz. The average electrical power consumption was measured by means of a simplified methodology. This power is assumed to be spent directly on the discharge generation and excitation of high-voltage pulses. The dependency of the consumed power as a function of the geometrical parameters of the DBD actuators is established. The specific power spent per 1 m of the length of the external electrodes is determined. Based on the measured air velocity profiles induced by the actuators and the integral momentum method, the volumetric force and the operating efficiency of the actuators were evaluated both at normal and low air pressures.
