Abstract

Impinging jets are widely used in ventilation systems in order to improve indoor air quality and energy consumption. Thus the flow dynamics involved in these configurations is very important and should be understood and controlled. In the present study, a plane jet issuing from a rectangular nozzle and impinging on a slotted plate was investigated experimentally by means of 3D-stereoscopic PIV. The velocity field was experimented for thirty parallel planes. The whole field was obtained by an interpolation between the reconstructed planes. The 3D reconstruction of the flow was obtained by using the phase averaging technique applied to each of the instantaneous fields. Self-sustained tones generated in this configuration were measured simultaneously with the PIV fields by the use of a microphone. The obtained acoustical signal was used as reference in the phase averaging technique.
