Abstract
Several studies have been carried out on the behavior of synthetic jets as a substitute of continuous jets. In addition, studies have also begun to control the fluid machine using the synthetic jets. The present study attempts to clarify the flow characteristics around a rectangular cylinder with symmetric/asymmetric slot for synthetic jets in a duct. The relation between flow characteristics of two-dimensional synthetic jets and the geometry of slots is investigated to apply the posture control of jet thruster. The influences of a beak-shaped slot on the behavior of synthetic jets are evaluated through experimental flow visualization using the smoke wire method and numerical simulations.
