An exact solution to the Navier–Stokes equation named for Lamb and Oseen describes the decay of one of these phenomena due to viscosity.
Generation of these phenomena are thermodynamically favorable at the critical temperature of the Kosterlitz–Thouless transition in the XY model. An exact solution to the Navier–Stokes equation named for Lamb and Oseen describes the decay of one of these phenomena due to viscosity. When a fluid flows on either side of some body and is separated, it can form a "street" of these phenomena named for von Kármán. Helmholtz names three theorems concerning these phenomena, the first of which states that the strength of one of their "tubes" does not vary in time. Their namesake quantity is equal to the curl of the fluid velocity vector. For 10 points, name these phenomena in which a fluid flows in a circle around some center.
