Development of the spiral structure
Image computed for every third unit of time ranging from 0 to
175.
We have suppressed the time independent average vorticity
represented
by w0 in the fourier coefficients to better visualize the roll-up of
the
vorticity sheets.
The distortion of the contours for small values of t is due to
a lack of sufficient convergence for the truncated Fourier series.
The series is not uniformly convergent and we have chosen to
concentrate
on values of t larger than 50.
