Abstract:
An experimental investigation of the sythetic jets generated by
plezoelectrically driven actuators with circular orifice is reported.
The investigation aims to provide information for active control
of boundary layer flows. Two different configurations of
synthetic jet actuator, single- and dual-membrane, were
investigated in conditions without cross flow. The mean and
volocity and local momentum along the centerline of the jet are
used to characterize the performance ofthe actuator. The effect of
amplitude and frequency of the driving signals on the actutor's
performance at Tollmiem-Schlichting frequencies is examined,
and the two types of actuators are compared.
