Collection description
The fluid dynamics research has been recently focused on the development of passive and active flow control technologies for drag reduction. Synthetic jet actuators overwhelmingly came out in the last years, due to their simplicity, wide velocity and frequency ranges and low weights, and they have been successfully employed in several flow control applications. However, a rational approach for the optimized design of synthetic jet for flow control is still lacking. The present research, therefore, has been devoted to refine existing models for the design of synthetic jet actuators, to characterize multiple-orifice devices for separation control applications and to investigate the receptivity of a boundary layer to synthetic jet actuation. The research aims at providing a rational procedure for the implementation of piezo-driven and plasma synthetic jet actuators in aerospace and automotive systems. The entire implementation process has been considered, starting from the preliminary design of the device, its manufacturing, its characterization, and finally the prediction of the actuator performances in operating conditions.
