Finite-time free-surface approach of a point stresslet
= Finite-time free-surface approach of a point stresslet
{title2=$h^3=h_0^3-3St/(32\pi\mu)$}
A positive-strength parallel point <stresslet> below a flat shear-free impermeable plane is attracted by its identical reflected image. Its height satisfies $\dot h=-S/(32\pi\mu h^2)$ and formally reaches zero in finite time. Negative strength reverses the drift. Finite-body near-contact physics lies outside this singularity prediction.
