These simulations are conducted in what could be called the
"Fiedler Can": |
The black contours show the fixed buoyancy field confined to
the vicinity of the central axis of the can. This image
also shows the vertical velocity early in the integration, at t=5.
A vortex ring is migrating toward the outer wall. A central vortex
has not yet "spun up", and the central vertical velocity has
stabilized with maximum value of 0.78.
The formal "thermodynamic speed limit" is 1.0. The figures
below will show the domain only with 0<r<0.5.
