In the viscous counterrotating flows, a level of nonrotating fluid (the exact location of which is influenced by diffusion) is always present. b. Two layer vortices—Rigid lower boundary.
WebBeckers et al. 5 and Godoy-Diana and Chomaz 13 have studied the effect of the Schmidt number on the decay of axisymmetric pancake vortices in a stratified fluid. It was found that for Sc > 1 the ... Webvortices decay much faster in this fluid than those in a viscous fluid. However such a result is shown to be true for a second-order fluid (see Markovitz and Coleman [7]) …
WebAs an outcome of diffusion and viscous dissipation of Karman vortices, the vortex street might be expected to disappear in far downstream (Zdravkovich, 1997). For flow past a circular cylinder for Reynolds number, Re 200, (Tritton, 1977) commented that `the vortex street continues to all distances downstream'. http://www.sciepub.com/reference/387024
