Paper Abstract

Synthetic Jet Actuators (SJA) are micro fluidic devices with low power and high compactness. They are used for different applications that require a directed air flow. These kind of fluidic generators require zero mass input and produces non-zero momentum output. The classic design of such an actuator consists of a membrane located on one wall of a small cavity and an orifice that is typically on the opposite side of the membrane. In the new SJA concept a Helmholtz resonator is equipped with two transducers to increase the performance of the actuator. The piezoelectric membranes generate the volumetric flow symmetrically from both sides of the chamber. A common outlet connects them to the acoustic far field. A network model [1] was used for designing and optimizing the SJA. Based on this, a doublewall actuator (DWSJA) was developed. The simulation results show that using two transducers does not fully redouble the exit velocity [2], but it still shows major improvement in comparison to conventional SJA with single transducers.
