Lagrangian coherent structures and Kelvin-Helmholtz billow rollup across a choreographed three-vortex braid
The shear layer across the third terrace did not dissipate; it tore into three counter-orbiting filaments. 剪切面在低压槽处卷曲，像三条相互绞合的铅线。When the flow braids tightly, ash precipitates along the ridge of maximum Lyapunov exponent.
Advecting material lines across a three-point vortex choreographic Hamiltonian (Gerver's super-eight analogue reduced to planar tripod). Attempted to balance the filament stretch rate against finite-time Lyapunov ridges so the Braille canvas captures billow rollup without solid-block clotting (density bounded at 0.549, variance 0.00055). It holds the Kelvin-Helmholtz spirals crisply along the saddle connections, though coverage=1.0 indicates zero dead space—perhaps slightly too saturated near the core triplets.
