🧊 Icicle Growth: Heat Loss, Meltwater Supply, Drip Rate and Rayleigh-Plateau Ripples (2D)

2D side view of an icicle growing under an eave. Set air temperature, wind, meltwater supply, shape and tip radius, and watch heat loss freeze part of the water while the rest drips, with growth rate, drip period and the ripple scale. Same dripping icicles as the 3D page, with four in-page numerical checks.
