On interpretation of flow visualization of unsteady shear flows

  • I. Gursul

Flow visualization of an unsteady wake is simulated by computer-generated streaklines and timelines, the two most commonly employed markers in laboratory flows. The resultant visualization patterns are compared with prescribed vorticity fields having constant or decreasing strength. Effects on the visualized flow of thickness and location of the injected marker, discrete (as opposed to continuous) marker elements, and different reference frames are addressed.
