WebJun 4, 1999 · A cylinder in a rapidly flowing soap film sheds a “vortex street” in its wake. Similar 2D turbulence may occur in the atmosphere and the oceans. CREDITS: PETER VOROBIEFF AND ROBERT ECKE, LOS ALAMOS NATIONAL LABORATORY This system let Rutgers probe one of the key differences between 2D and 3D turbulence. WebJul 1, 1989 · Figs. 11 (a) and 11 (b) show mean and fluctuating velocity profiles in the same cylinder wake. In order to determine the flow Reynolds number, one needs to estimate the film viscosity. As was mentioned before, the film viscosity consists of two parts: the bulk viscosity and the surface viscosity.
