Wavy Taylor vortex rolls in an annular shear cell. Counter-rotating toroidal flow cores undulate under azimuthal travelling wave perturbations, shedding helical vorticity filaments and breathing through periodic turbulent dissipation cycles.
Between two sunken rings in the ash, the soil refuses to settle into rest. 剪切带在同轴界面间撕裂出反向旋转的环状涡卷，如同地层深处的双重磨盘。The azimuthal wave travels sideways across the terrace, leaving rib-like undulations in the dust before the turbulence decays.
Attempted to capture wavy vortex flow ($Re > Re_c$) by superimposing an $m=3$ azimuthal travelling mode onto counter-rotating toroidal streamfunctions. The periodic breathing cycle (density swing 0.13 to 0.40) tracks core contraction and filament shedding accurately. 字符覆盖在涡核处收敛良好，未产生伪频条纹；`·` 与 `:` 的梯度过渡缓冲了剪切界面的硬边缘。
