Let z denote the axis of symmetry and r measure the distance to the z-axis. Suppose the solution satisfies, for some 0 ≤ ε ≤ 1, |v (x, t)| ≤ C ∗ r −1+ε |t|−ε/2 for − T 0 ≤ t < 0 and 0 < C ∗ < ∞ allowed to be large. We prove that v is regular at time zero.en-USAxisymmetricBlow-up rateLower boundsNavier–Stokes equationsRegularityLower Bounds on the Blow-Up Rate of the Axisymmetric Navier–Stokes Equations IIJournal Article2017-05-1810.1080/03605300902793956
