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. florian winkler twitter

Web7 de jun. de 2016 · An experimental investigation of the viscous decay of a steady, three-dimensional, helical vortex is presented. The vortex was generated by a rectangular, symmetrical half aerofoil (N.A.C.A. 0009) of 10·5 in. span, 3 in. chord, cantilevered from the wall of the circular test section of a low speed wind tunnel. Only the local total head and ... WebThe decay of two counter-rotating point vortices of equal strength in a viscous incompressible fluid is studied by solving the Navier-Stokes equations with a finite … WebThe evolution of a viscous vortex pair is investigated through the use of a heuristic model. The model is based on the linear superposition of two Oseen vortices of opposite circulation spaced a distance 2b apart. The vortices are allowed to evolve through viscous diffusion and their mutual induction. The motion is unforced and as a consequence the total … florian winath
