On the vortical structure in a plane impinging jet [PDF]
Journal of Fluid Mechanics, 2001 The vortical structure of a plane impinging jet is considered. The jet was locked both in phase and laterally in space, and time series digital particle image velocimetry measurements were made both of the jet exiting the nozzle and as it impinged on a perpendicular wall.
