In order to reveal the flow structure of the jet issuing from the pentagonal duct with and without the synthetic jet, the flow visualization was conducted. Moreover the velocity measurements of the jet flow were performed by using the PIV method. The jet diffusion was investigated by analyzing the velocity distributions. To excite the share layer of the jet, the synthetic jet was spouted from the actuator set on the outside of a vertex of the duct exit at 0 or 45 degree angle with respect to flow direction. As a result, it has been found that the jet diffusion adding the synthetic jet in jet middle-plane is promoted.
