In some configurations, a plane jet hitting a slotted plate produces noise. In this study, a particular attention is paid to the interactions between vortices that are developed in a flow generated by a rectangular jet impinging on a slotted plate and the geometry of the plate. An experimental device based on the 3D Particle Image Velocimetry (PIV) is used. The analyzing of the images obtained by the PIV technique allows us to detect and follow vortices in time. Thus, the correlations between the production of noise and these vortices will be analyzed when they approach from the slot of the plate.
