This animation if picture
with a 0.025s time step show the evolution of the x-velocity. Unfortunately
colors may designate different speeds from one picture to another. Notice
the growth of a transition zone (in green and yellow) and the spreading
of the hot spots that a turning into wide and diffuse zones. It is also
interesting to monitor the peek velocity that vary from 1,36 m/s at t=0.05s
to 1.11 m/s at t=0.225s that confirms the global evolution towards small
speed gradients after the period where the vortex is rapidly growing.
