Rb. Pelz et Y. Gulak, EVIDENCE FOR A REAL-TIME SINGULARITY IN HYDRODYNAMICS FROM TIME-SERIES ANALYSIS, Physical review letters, 79(25), 1997, pp. 4998-5001
The multiple-precision time series solution of the incompressible invi
scid flow equations with the initial velocity field u(x, y, z) = w(z,
x, y) = sin x (cos3y cosz -cos y cos 3z), has been computed to 32 term
s and maximum wave number 99. Ratio test and Pade analyses indicate a
real-time singularity in enstrophy Omega(t) with the form (t(crit)(2)
- t(2))(-1) where t(crit)root Omega(0) congruent to 4.
