On the decay of vortices in a viscous fluid
WebAbstract The energy decay of vortices in viscous fluids governed by the compressible Navier–Stokes equations is investigated. It is shown that the main reason for the slow … WebSolutions of the Navier-Stokes equations are obtained for the flow of an isolated, trailing vortex, and for the swirling flow through a frictionless pipe. In both cases, the flow is assumed to be steady, incompressible and rotationally symmetric. Solutions are computed using Newton's method and Gaussian elimination for a wide range of values of two …

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'.

For the smooth case, the blue line first diverges from the laminar stage and increases sharply at about x = 205 mm. At about x ... After x = 330 mm, the skin friction decreases, which is caused by the decay of Görtler vortices.

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]) which is a viscoelastic fluid (with small memory) pro- vided the time scale which characterizes the memory of the fluid and the size of the vortices obey certain restrict- tions.
