= Self-similar ice-bearing wall plume
{title2=$b=eZ,\quad w=(g'I_0/e)^{1/3},\quad\phi=w^2/(g'Z)$}
For one exposed entraining edge and conserved positive dilute ice flux $I_0$, the line-plume equations give the displayed pure far-field solution. Its width grows linearly, speed is constant and ice fraction decays inversely with distance from a virtual origin. Two exposed edges replace $e$ by $2e$. The dilute solution is invalid near the formal origin, where its ice fraction diverges.
