NAVIER–STOKES
SWIRL

Inward motion. Outward stretch.
A vortex in constant circulation.

Viscosity ν0.060

Less viscousMore viscous

Higher viscosity spreads the core and softens its rotation. Values use relative units.

Singularity

Explore a shrinking, accelerating core as time approaches the singularity.

Flow guides

Analytic vortex visualization. Singularity mode illustrates scaling, not a numerical solution of the full proof.
