Abstract

An experimental study of an excited jet interrupted normally by a 90° sharp edge is described in this paper. Based on schlieren technique, it is possible to distinguish three flow regions: the main jet flow, the wake flow behind the sharp edge and the redirected flow on the surface. By following the individual articially excited jet vortices, it is possible to observe the structure and to estimate the convection velocity of these vortices in the three flow regions. By comparison with the results of the uninterrupted jet, the effect of the sharp edge is obtained and presented.
