Abstract : an understanding of vortical structures and vortex breakdown is essential for the development of highly maneuverable and high angle of attack flight. this is primarily due to the physical limits these phenomena impose on aircraft and missiles in extreme flight conditions. Velocimetry is used to determine the characteristics for three regimes of the flow: the upstream region, effectively the initial condition of the parallel vortex pair; a midstream region where the vortices are interacting during the linear regime of the instability; a downstream region where the vortical flow is strongly three dimensional.

The unsteady three dimensional flow interactions in the near field of square and circular jets issued normally to a crossflow were predicted by direct numerical simulations, aiming to investigate the effect of the nozzle cross section on the vortical structures formed in this region. the analysis focuses on jets in crossflow with moderate reynolds numbers (rej=200 and rej=300) based on the jet. This provides depictions that both convey the subtle struc tures present in vortical flows, especially during vortex breakdown, and provide an intuitive understanding of their spatial context and associated physical properties. Following the observations of werlé, mechanical and or pneumatic devices are the primary methods used to control the vortical structures, the corresponding vortex breakdown, or the flow characteristics which can alter the influence of these phenomena on the wing or aircraft in question. This study reveals the separated vortical flow with vortex breakdown and a wave like structure in the flow visualization images. this wave like structure is found to be related to the onset of vortex breakdown over the flying wing configuration.
