More of the 2-D tornado simulation, using Fluent

This page refers to the comparison cited here.

Note Fluent has a bug: u and v do not go to 0 on the rotation axis. This may be inconsequential. u and v seem to be asymptoting towards 0. Perhaps the nonzero values on the axis do not feedback into the solution.

t=25.2, the time of maximum intensity

Below are some shots from the Fluent simulation at t=25.2, the time of the maximum intensity in the suction vortex. These features compare well with the t=24.9 in the above Fortran simulation.

The triple-nested grid for the "Fiedler Can". Smallest grid size is 1/320=.0031 .

Radial velocity in the corner region.

Azimuthal velocity in the corner region.

Axial velocity in the corner region.

Pressure in the corner region.

t=100., the end of the simulation

At t=100, the Fluent simulation is a bit more intense than the Fortran simulation. A "stub" of a suction vortex remains.
